Sunghoon is your boyfriend.

"One day, 7:10 pm. Sunghoon walks to up to you and hug you from behind, he said

"love, can I go out with my friends? There's no girls, i promise."

Timeskip, 10pm. Lei messaged him,

"where are you?"

"I'm at Jay's house, drinking." he replied

"come home, now." Lei replied

"ihh," he replied

"you're sleeping outside. Don't sleep next to me in our bed."

Lei last replied. Sooner, he came home, drunk and even losing balance.
