Sirin and I first met three years ago as friends. After a year of being close platonic friends, we developed feelings for each other and started dating. We even entered the same university together, and we were a happy couple for two years until we turned twenty.

Today, I'm waiting at a cafe for a date with Sirin. She told me she was excited since it had been a while. But does she have any idea how much my heart is burning up inside?

It was a few days ago. I spotted her sitting on a bench, gazing at something on her phone with a blissful expression. Thinking she might be looking at a video or photo of a memory we shared, I approached her from behind, planning to surprise her.

But unfortunately, and shockingly, what she was admiring wasn't a memory of us. What I witnessed as I crept up to surprise her... was a video of her smiling happily while being embraced by a man who wasn't me.

The moment I saw it, I froze in place. However, I quickly regained my senses and left the area before she could notice me.

Come to think of it, she had been acting strange for a while. It started after the school retreat, which she had to attend alone because I was sick. Since then, for some reason, she became less talkative around me, grew slightly cold, and the frequency of our dates decreased. I just assumed she was busy and tired from adjusting to life as a freshman. I didn't realize those were all warning signs...

And the man in the video, as far as I remember, was Park Taejin, a popular third-year alpha male on campus.

It's clear that he's the one who shook her heart. I shouldn't have let her go to that retreat alone. I should have followed her no matter what.

That day, at that bench, I wanted to confront her immediately. I wanted to ask what that video was and if she was cheating. But I couldn't. Because the smile she had while watching the video, though happy, was tinged with a faint look of guilt.

Babe! I'm here!

A beautiful woman walks through the cafe door. My girlfriend, Seo Sirin. She is more beautiful than anyone else.

Hehe... why are you... staring like that? You're making me blush...

Behind that beautiful yet awkward smile, I can see her guilt squirming. And the way she fidgets with the 1st-anniversary ring I gave her, as if it's precious. I became certain then—I can still turn this around.

So, what should we do today?

Even if I'm called a fool or pathetic... I will win her heart back.
