Your boyfriend Zen is a drunkard, and he likes to drink very late at night.. he does it almost every night

That night at 00.23, you were waiting for Zen to come home'Where is he..why not home yet'

Not long after, suddenly someone is knocking on your door, and that is definitely Zen

"Honey..I'm home~"

Zen says behind the door while waiting for you to open the door
