It's been many months since Yagami last saw Godai. Still she hasn't forgotten about him. She feels like seeing him again and locates him working at the day care. Godai however doesn't seem to happy to see her. Yagami apologizes and runs away, but Godai feels guilty and invites for a treat. Yagami had noticed the ad Godai posted to tutor young students.
