My best friend's brother and I have been dating for half a year, and she has no clue.

My best friend drags me out on Christmas for a singles' night out. Unexpectedly, we see her brother, Chris Lambert, holding hands and kissing a girl under the fireworks.

"Damn, Chris finally got the school belle!"

She looks thrilled and pulls me forward to say hi.

Chris awkwardly rubs his nose and introduces me to his girlfriend, "This is my sister, and the one beside her is… sort of like my sister too."

I smile silently.

We have held hands and kissed, yet now, I am just sort of like his sister.

After my best friend, Tricia Lambert, had a breakup, she dragged me along with her to spend Christmas together. She aptly called it having a "single women's night out", and we went to see the fireworks show that was being put on for the festivities.

However, the truth was that I had been secretly dating someone for six months without telling her.

Thus, I went out with her with a guilty conscience.

In the midst of the crowd, Tricia suddenly pointed ahead and exclaimed in surprise, "Damn! Isn't that my brother?"

I followed her gaze and saw a tall, eye-catching figure in the crowd.

I knew that figure very well—it was Chris Lambert, Tricia's older brother. He was even wearing the black puffer jacket that I'd given him.

Since he couldn't spend Christmas with me, I had given him his gift in advance.

Indeed, the boyfriend I had been hiding from everyone was my best friend's brother.

But why was he here?

Just as I was wondering, I heard the sound of fireworks exploding.

The sparks streamed across the night sky like scattered stars. Couples around us hugged and kissed each other, seemingly trying to freeze time in this fleeting, romantic moment.

Chris was no exception. He turned to the woman beside him, gently cupped her face like she was a treasure, and kissed her.

It felt like a jolt of electricity ran through my whole body.

So, he hadn't come alone.

He had turned down my Christmas invite, claiming to work overtime, just so he could watch fireworks with another woman.

It truly felt like the moment had been frozen in time. I couldn't hear the surrounding noise or see the fireworks.

The cold wind stung my eyes as the sight of the sweetly kissing couple slowly blurred before me.

Tricia pounded on me excitedly. "Oh my gosh! That's Yvonne! Chris finally got the school belle! Can you believe him?"

I looked up at the dazzling scene, trying hard not to let the tears in my eyes fall. I just wanted to run away.

However, Tricia grabbed my arm and dragged me forward through the crowd.

"No can do! We already ran into him, so now he owes us a late-night snack!" she said excitedly.

By the time we got to Chris, the fireworks had just ended. The night sky returned to silence, and the two pulled apart, but their hands remained tightly clasped.

Tricia suddenly slapped his shoulder. "Caught you red-handed! Aren't you going to introduce us?"

Chris turned around and froze when he saw me. He rubbed his nose awkwardly and blurted out, "What are you two doing here?"

Tricia shouted at him, "What, are single people not allowed to see fireworks on Christmas? Quit dodging the question and fess up!"

Chris pulled his gaze away from me and looked gently at the blushing woman beside him, saying, "This is my… girlfriend."

Then, he wrapped his arm around her shoulder and softly added, "That's my sister, and the one beside her…"

Both of them focused their gazes on me, and I felt my eyes sting. I immediately lowered my head.

I heard Chris introducing me, "She's my sister's friend, so she's kind of like a sister to me."

Yvonne shyly greeted us. "Hello. My name is Yvonne Simmons."

Tricia snickered and said, "I knew it! Chris has liked you for ages. He even showed me your picture and couldn't stop talking about you."

To avoid exposing our relationship, I almost never appeared when both siblings were present together. Even when chatting with Tricia, I tried to steer clear of any topic about Chris.

It turned out Chris had secretly liked Yvonne for a long time, huh?

Then what was the point of carefully hiding what we had for the past six months?

I took a deep breath and forced a smile. "Chris and… Yvonne, Merry Christmas to you both."

As soon as I spoke, I realized my voice was trembling.

Ten minutes ago, I had received a message from Chris.

He said, "Sorry, babe. I'm really busy this year and don't have time to be with you. I'm still buried in work right now. Hope you have a happy and unforgettable holiday."

He really did give me an unforgettable Christmas, relegating me as his "sister" in such an awkward moment.

When Yvonne heard the tremble in my voice, she quickly asked if I was feeling cold. "The weather has gotten really chilly. Let's find somewhere to sit and chat."

Before I knew it, they had pulled me into a barbecue restaurant and sat me down.

Under the warm lights, I finally could get a clear look at who was sitting across from me.

Yvonne was truly beautiful. Her eyes seemed to sparkle, and two small dimples appeared when she smiled.

She leaned in toward Chris and whispered, "I kind of want some fresh barbecue, but don't you have to rush back to the law firm to work overtime? We should be able to make it, right?"

Chris had recently told me that the firm had taken on a big case and that everyone was working late into the night.

But to my surprise, he gently tucked a loose strand of her hair behind her ear and softly said, "It's okay. I want to spend a bit more time with you."

After speaking, he glanced at me—whether it was casually or deliberately, I couldn't tell.

However, it was only for a moment before he looked away again.

I had never seen this side of Chris before. In the six months we were together, he always prioritized work.

Once, he forgot about my birthday because he was working day and night on a report. Another time, he left in the middle of a date without a word just to answer a work call.

It wasn't that I never got mad, but he would always calmly say, "I work hard to build a better future for us. After all, a stable future is the foundation of a relationship."

I foolishly believed him and never argued again, so I held back all my negative emotions alone.

But at this moment, I finally understood. If a person truly loved someone, they would find a balance between career and love.

Being busy didn't mean you couldn't wish someone a happy birthday, and no matter how urgent the work call, you could always just explain the reason before leaving.

It was just like now—the longer Chris stayed here, the later he'd get back to work. And yet, he still didn't want to disappoint Yvonne and chose to eat with her.

A loving relationship versus one with a lack of love was really obvious.

When I saw him like this, I suddenly understood—he just didn't like me enough.

Tricia chirped nonstop, asking all about their love story.

Yvonne was very sweet and answered every question.

"We met in school. He was the president of the debate club. I guess we're alumni, huh?"

"Chris has liked me for years? I didn't know… He never showed it. I always just thought of him as a really good friend."

"Today's our first day together. He started asking me to spend Christmas with him a month ago, and… He just confessed earlier."

Yvonne's tone sounded shy and sweet, just like every girl in love.

I listened in a daze.

Love at first sight, silently protecting her, and a secret crush come true—if I weren't unwillingly caught up in it, I might have thought this was a pure and romantic love story.

Unfortunately, this man who now treated his girlfriend so tenderly had told me he loved me when he bid me goodnight yesterday.

This meal truly was painful to get through.

After the dinner finally came to an end, Chris said he would first take Yvonne home before returning to the law firm to work overtime.

The law firm was very close to my home, and Tricia gave me a push toward Chris.

"I'll head home first. Chris, since you're working late anyway, just give Yara a ride too," she said.

Chris frowned ever so slightly. He was just about to speak up in refusal when Yvonne smiled and took my arm.

"Let's go together," Yvonne said.

Chris said nothing after that.

I had intended to refuse, as the thought of the three of us being in the same confined space felt suffocating.

But on second thought, it shouldn't be me, the one who was deceived, feeling awkward.

I could be sad, and I could be angry, but I definitely shouldn't run away from the situation.

After we got to the car, Chris thoughtfully opened the passenger door for Yvonne and bent down to fasten her seat belt.

I sat in the back seat, watching as Yvonne skipped my favorite song and switched to her own playlist. She moved with practiced ease, and it seemed she had ridden in this car many times before.

Back when we were in the early stages of our relationship, Chris often drove to pick me up from school.

But over the past month, he had rarely met up with me and always blamed work.

Only now did I notice that the cute handmade decoration I'd given him was nowhere to be seen. Even the good luck charm I had painstakingly gotten and hung in his car had disappeared.

I stared at the fleeting cityscape outside the window, struggling to suppress the ache in my heart.

I remained silent the entire ride.

When we got to Yvonne's home, she opened the back door of the car. Because she thought I was carsick, she generously invited me to sit in the front.

I declined, but she smiled and said, "I'm not one of those girls who think no other girl can sit in their boyfriend's front seat."

But I had already sat there many times—back when Chris was still my boyfriend.

After Yvonne left, it was just the two of us in the car. Chris didn't start the car right away.

He kept tapping the steering wheel with his fingers. It was a sign that he was agitated.

After a long silence, he finally said in a low voice, "Yara, I'm sorry."

He didn't even dare look me in the eye.

I let out a soft laugh and stubbornly asked, "Besides apologizing, don't you have anything else to say?"

I knew perfectly well that no explanation could justify any of this, but in just these few hours, countless memories flashed through my mind.

Chris had once returned from a business trip late at night just to surprise me downstairs at my place. He used to share little bits of his daily life and would even take pictures of dogs he saw on the street just to show me.

Were we ever truly happy? Did he treat me well?

The answer was yes. Otherwise, I wouldn't have foolishly kept our relationship a secret for half a year.

I just wanted to hear him say something, anything, to give this hidden relationship a proper ending.

Chris rolled down the window, lit a cigarette, and stayed silent for a long time.

When the cigarette burned out, he finally spoke. "I liked her for many years, and we were in the same department. However, she had a boyfriend. I knew we had no chance, so I never confessed.

"Later, when I was with you, I thought I was doing alright, and I truly did consider a future with you. But then… She became single again.

"When she cried and told me about her breakup, I felt a mix of emotions—pity for her, guilt toward you, and even relief for myself. I felt like… maybe we finally had a chance. Whether it was love or obsession, I just didn't want to miss my chance again.

"The only person I truly wronged was you, Yara. From now on, can I treat you like a little sister, just like Tricia is to me?"

I almost laughed when I heard his excuse, and I asked in return, "So, when you said we'd go public once our careers were stable, what you were really hesitating about was that slight chance with her, right?"

This time, Chris stopped talking altogether.

I knew then that I had guessed right.

Being in a relationship that only the two of us knew about didn't stop him from continuing to like someone else. In fact, ending it was easy for him.

He had always harbored hopes for him to get with Yvonne deep down, and in order to appear devoted in front of her, he had lied to me from the very beginning.

Whether he had genuine feelings for me or simply saw me as a distraction no longer mattered to me.

There was no real difference either way.

In the end, it all came down to my poor judgment. I had placed my trust in the wrong person.

The smell of Chris's cigarette drifted over, and I belatedly felt sick to my stomach. I pushed open the door and got out of the car.

He said he'd drive me home, and his car slowly trailed behind me.

However, I didn't want to say a single word to him. Instead, I turned around and kicked the car door hard. That finally made him drive off.

Through the rearview mirror, I could see the ugly expression on his face.

I was the only one walking the streets aimlessly on a festive night like this, in such biting winter cold.

Scalding tears streamed down my cheeks and burned against my skin.

I was in so much pain, and the more I cried, the louder I became.
