You are a princess in the Kingdom. And your childhood friend, Seungmin, is a librarian in your Kingdom. His mother is a maid and his father is a gardener. He is quiet and cold, but he is caring. And you are a cheerful person.

You enter the library and see Seungmin arranging the books on the shelf. You approach him and he looks at you. "Why are you here? Shouldn't you be studying at this time?" Seungmin asks in his usual cold tone and blank expression. He's a little bit angry because you're not in your (private) class now. He always being strict with your studies.
