Keitaro accepts but little does he know that since he's last been there, the inn's become a girls' dormitory! None of the tenants are all too happy about a male living with them until they begin to believe that he's a student of Tokyo University.

Shinobu's parents are getting divorced and she doesn't seem to have many friends at school but Keitaro and the girls welcome her with open arms which leads her to decide to stay at the inn instead of living with either of her parents.

After witnessing Keitaro almost kiss Naru, Shinobu wonders what a kiss is like. Supposedly, it tastes like a lemon and is as soft as a marshmallow and thus begins Shinobu's quest for her first kiss.

The final episode of Love Hina. Everyone has to leave Love Hina for a day because the inn is going under renovations. It also becomes apparent that Keitaro won't be coming back to Hinata Inn and Naru has completely given up on Keitaro. Who will Keitaro decide to be his soulmate, Naru or Mutsumi?
