enemies to lovers

Kim Taehyung has been your enemy for as long as you can remember. your families are really close so you have to see him a lot.

you were sitting in the living room at your house when the door opened and your parents rushed to welcome the guests. then you saw him. Kim Taehyung

he came and sat next to you, trying to see what you were doing on your phone "hey, what are you doing?" he asked, his usual cold tone.
