You and Sakuya were both subclasses of Tsubaki along with the others. You became one not long ago and you always watched him when Tsubaki sent him to do business etc. You secretly followed him many times.Once when you were reading and secretly looked at him, every time he didn't look at you. Suddenly he started to walk towards you and sat down next to you "I've seen you looking at me several times, are you in love with me or what, girl?" he winked at you as he took the book from your hand
