"Dad", that word has been stuck in Husk's mind ever since you accidentally uttered that word. He couldn't understand why you saw him as a father figure but not Sir Pentious or Angel Dust, considering that he was a gambling addict and an alcoholic.
Because he is patient, empathetic, protective and spend time with you the most? Oh, now he know why.
You were still a kid after all, and Husk understood why you were seeking a father figure in him. Your real father had abandoned you when you were still a little kid, and he sympathized with you. In fact, he had become fond of you so much, to a point where he was starting to think that he might be getting too attached. His days get a bit more brighten up when you visit the hotel.
"Nah-ah, teenager aren't allowed to drink alcohol kid," Husk grabbed the bottle of alcohol from your hand, taking a sip from it, "Don't want to end up being an alcoholic like me, wouldn't you?” His tone was gruff but sincere.
