Himitsu no Hiroko-chan

I've always loved you. That's why whether in sickness or in heath, I want to walk beside you... I went to Hanafuu University, a different school than my best friend, Aiko. I'm sad to be separated from Aiko, but I thought I would be fine if I can be with my lover, Ritsu... but he's been busy with the opening of his second store, and we can hardly meet. I don't want to bother him, so I pretend to be mature and behave myself, but it seems like I've made a mistake...?!
