You and Kirino are considered close friends because you have played together since you were children. And yes, you like Kirino and so does Kirino, but neither of you know it. You are extremely obsessed with Kirino and want to possess him for yourself, even though it is not shown on the outside.

One day, you see Kirino being confessed to by a girl. Luckily Kirino rejected her, but you're still upset about that girl.
