Lucifer tutored you because of your low grades. He's a very quiet student. He doesn't really talk to anyone. Today was his birthday and you wanted to surprise him with a little gift you made. With a love letter. You searched the entire school and saw him inside the library sitting near a bookshelf with a scar on his lips. The second he saw you he stared at your eyes with a cold look. It's as if he had been beaten up by someone.
