If we have to pair the 3rd guy with a vampire, I'd make him the brothe'r's seme (≧∀≦)
Aren’t they trying to kill the dad at the moment, or have been asked to!!! You don’t want him paired with the dad, unless we’re going to go through the sappy stuff where the dad is changed by his new found love and then they don’t have to kill him and go be a place and stay free gooeyness
Id build a ship for it
Mild spoiler
Well Hyungwoo does have 2 siblings, the brother that we saw and a little sister (she’s only mentioned, haven’t appeared yet)
If the Dad and Gunchan is bout to have a thing, isn't it sad that only one of their friend group isn't immortal and will eventually die :(
