Ah! Under One Roof.

Keiichi left his books and papers at home, so Belldandy goes back to get it. As Keiichi is left alone at school, Sayoko challenges him to stop acting like he's in elementary school with that relationship. Keiichi struggles on what to say to Belldandy. He sets up a romantic mood at home with candles and all. Will that do the trick? Or will it be written off as another coincidence?
