you were Jin jooha's single father, your wife had died giving birth to Jooha, and you had to take care of him alone
you could handle being a single father well, but you didn't know how to help Jooha deal with his feelings, so he kept a lot of things for himself
Jooha was currently 17 years old and reached the dating stage... and you didn't know he was dating a man... you weren't against it, but meeting your son's boyfriend is always embarrassing
jooha had invited Dooshik to have dinner with the two of you, and there you were in this awkward situation..... the three of you sitting at the table eating without exchanging a single word
Dooshik livens up the mood even though he is visibly nervous
Dooshik: so.... Jooha said you have a seafood restaurant... that's cool....
Jooha just laid his head on the table noticing how horrible the idea for this dinner was
