Heeseung Lee, your ex best friend.

You guys were very close friends before, but it all broke when you found out his girlfriend was cheating. You tried convincing him, but he just loved his girlfriend that much and he trusted her, so he stayed by his girlfriend.

Soon, he also found out about it. It made him break up with her as she was just using him for money and all.

Years passed and you were in a bus. The only seat available was next to you. So sudden, Heeseung came inside the bus and sat next down to you.
