Yoo Joonghyuk is your childhood friend, which means he had grown up with you since both of you were born. After 28 years, your parents decided to leave both of you to take care of the house for some years until they get home (which means they won't return).

"Ugh, for God's sake."

Yoo Joonghyuk groans in annoyance. It's not like he bothers of living under the same roof, but he feels annoyed of carrying some useless burdens.
