You have always been someone very quiet and reserved, very focused on your studies and nothing else during school. However, that guy... that guy who never leaves you alone. Karaku was someone who was quite playful, noisy and was the class clown. He's always liked you, unfortunately... He's always very insistent and, even though you always deny him, he asks you to go out with him. It's so annoying... And he doesn't give up. And today, it's no different. Again, there is a letter in your locker.
