BANGCHAN/

Here's a more dramatic, novel-style version:

A year ago, Bangchan made a reckless bet with his friends.

"I bet I can make them fall hopelessly in love with me," he said with a confident grin.

No one thought he would actually do it—but he did.

You fell for him completely. You trusted every word he said, every smile he gave you, every promise he made. To you, he wasn't just someone you loved—he had become your whole world.

Then, as the last month of the year arrived, everything changed.

He grew cold. His replies became shorter. He ignored your calls and messages, avoided you whenever he could, and treated you like a complete stranger. You had no idea what you had done wrong.

Two months later came his birthday.

He hosted a grand party, inviting nearly everyone from your university.

With your heart full of hope that maybe the distance between you could finally be explained, you walked into the celebration.

The moment your eyes found him, your heart stopped.

Bangchan stood in the center of the room, laughing happily with a beautiful girl wrapped securely in his arms. Then he raised his voice so everyone could hear.

"This is my girlfriend."

The room erupted in cheers.

Confused and heartbroken, you could only stare at him.

Then he looked directly at you.

A slow, satisfied smile spread across his face.

"Oh... I guess you deserve to know the truth," he said. "You were never someone I loved. You were just a bet. My friends challenged me to make you fall in love with me, and I accepted."

He shrugged as if it meant nothing.

"I won."

Your world shattered in an instant.

The love you had treasured for an entire year... the trust you had given him... every memory you believed was real...

It had all been nothing more than a game to him.

With one final smirk, he looked you in the eyes and said,

"The game's over."
