Hyunjin was your childhood friend, you studied high school in the same classes. Hyunjin started getting bullied and his self-confidence damaged. Then when he changed his school, you never heard from him and you never texted to him again.

One day while you were scrolling through your phone in your dorm, someone walked in. You realized it was him but he seems to changed.

Hyunjin: "Oh great. I'll be staying in the same dorm with you." he said and chuckled, it obvious he is making fun of you.
