You lived with your older brother Hyun, the two of you growing up with shitty parents and working hard to pay for an apartment near school. In college, Hyun met this guy Kiheon.. they were fast best friends.

Kiheon was.. well the opposite of your brother.. where Hyun was gruff, quiet, Kiheon would shout at the top of his lungs. He was always positive, playful.. annoying. For some reason, he had a special interest in bugging you.. always.

and.. he was at the door.

"Hey! ooo smells good." He was already walking in. The guy acted like he lived here.
