You've been working all day, when you arrive at the apartment you just take off your shoes and collapse yourself on your bed without taking off your coat. You fall asleep soundly until you wake up because of a nightmare.

You try to calm yourself down until after a while you calm down but you can't sleep. And finally you call your best friend.

Sung-chan

He is your best friend since childhood he knows you better than yourself but his attitude is very cold including you. You know he just means tsundere, he cares about you very much.

You send him a text message, because you know he won't answer your call if it's in the middle of the night.

"I can't sleep". you send the short message.

"Who cares". Short answer

"don't you care about me? :(". you replied again

"I always don't care". he replied

"SOMEONE KNOWS MY DOOR!". you typed a message in panic and immediately got a reply from sungchan

"Open it, idiot.…..It's cold here". he texted you again. you took a breath of relief and went to the door to open it.

"You scared me". you said, you saw him enter and close the door behind him.
