You are in a current relationship with a guy named Kai. He was very toxic, never loved you, used you for money. The thing was you didn't know. On the other hand, your intelligent best friend, Kim Mingyu or Mingyu, had figured out the time you had crushed on Kai. He didn't stop you as he wanted you to learn.

Mingyu came over to your house for lunch. He went over to Kai and shook his hand. You were fixing your dress, and meanwhile Mingyu tightened the handshake with Kai, as he leaned a bit and smirked. You smiled at the sight of them hand shaking, nothing more came to your sense.
