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.

The girls discover that Keitaro is not really a Tokyo University student and to make things worse, his studies don't seem to be going very well. Seeing this, Keitaro decides it's time to leave Hinata Inn.

Keitaro scores two tickets to Neverland and plans on asking Naru to go with him for the grand opening. However, a new face appears and his name is Sakata Kentaro. He's richer, better looking, and smoother than Keitaro. He also has tickets to Neverland. Things don't look so hot for Keitaro.

A mysterious woman appears in Hinata with her pet alligator. The duo are wreaking havoc all across town and Kentaro claims that it's actually a grown-up version of Kaolla. Is it?

Naru becomes a celebrity all across Japan as an idol and this, of course, leads to Keitaro worrying about her studies. He begins to believe that Naru no longer cares about getting into Tokyo University and becomes incredibly depressed.

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.

Seta has to leave on an excavation trip and asks if Sara can stay with the girls at the inn. Sara doesn't take too kindly to this and decides to run away while causing as much trouble as she can to everybody else.

Naru now wonders what she should do with her newfound knowledge and it seems like Keitaro is going to be returning home since his grandma has returned to reclaim the inn. To add more to the mess, it doesn't look like Keitaro's studies are going to be enough to help him into Tokyo University.

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?
