Yang Jeongin ⁻ ⁽⁰²⁾

A few days ago someone moved into the apartment next door, you didn't care until you saw the attractive guy who was separated from you by only a wall.

Every day you greeted him hoping he would answer, and he did.

You fell madly in love and decided to write her several letters that you didn't dare deliver, until one day you decided to leave one under her door, the door of apartment 512...

Later someone knocked on your door, to your surprise it was Jeongin.

-"Hello."
