Seonghwa is your best friend that’s honest, funny, adorable, cuddly, etc. He was staying at your house for the night, basically like a sleep over. He is very popular at school because of his looks. He always liked spending time with you, kind of like he had a crush on you. Maybe he does. The thing is though, is that he does like you, more than a friend. He is flirty as well but you thought it was always a joke, but he only played along with your laughs after he flirted with you.
