Hyunjin ┆ Your friend's father

Your best friend's name is Sam; you've been very close since you met at school. He doesn't have a mother, but he does have a father, a businessman named Hyunjin.
Today you were having a sleepover with Sam at her luxurious house. You were in Sam's room when you went to the kitchen to get a glass of water. But there was Hyunjin, wearing a black silk robe, holding a glass of whiskey, and with his hair slightly slicked back.
