Hinata Inn is having a financial crisis and everyone must take up a part-time job. When Keitaro becomes an assistant for Naru's first love, Kitsune becomes incredibly worried and curious at the same time about what might happen when Naru discovers that Seta is back in town.

When Keitaro has to take care of Seta's adopted daughter, Sara, Naru of course finds out about Seta. Keitaro begins to give up his hope of Naru ever liking him and decides to help her be happy instead.

The tenants of Hinata Inn are working part-time at a beach tea house and decide to perform a play to increase revenue. Keitaro is still incredibly glum about the whole Seta and Naru situation and it's pretty understandable.

Naru becomes possessed by an evil spirit and Motoko is the only one who can destroy it. Unfortunately, she doesn't know the technique to kill the spirit without killing the body and it's quite a predicament.

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.

A man who happens to look exactly like Keitaro when he wears glasses appears and is later found out to be from Kaolla's home country. He is here to get married to Kaolla but she decides she isn't quite ready yet, but tradition says she must.

Keitaro discovers a doll that can move on its own. Everyone is amazed by it but Keitaro seems to be able to hear it talk also. He finds out from the doll that his great grandfather promised to fix its legs but never did and being the good guy he is, Keitaro decides to fulfill his ancestor's promise.. With the help of the girls, of course!

Naru and Keitaro decide to go out to celebrate the latest grades and while both are wondering whether it's a date or not, a mysterious little girl appears.

Mei is Naru's stepsister and hopes to take Naru back home. To accomplish this, she decides she has to hook Keitaro up with Mutsume and it is in this episode that Naru finds out something shocking.

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?

Keitaro decides whether or not to confess his love to Naru. Eventually he confesses, but Naru's reaction is not as he had hoped.

Keitaro and Naru are taking the second exams. Keitaro takes a look at the exam and has confidence that he can pass it. Then he starts daydreaming about how he and Naru will get married afterwards, then he wakes up and the examiner announces there are 5 minutes left. Keitaro runs away and applies for a job overseas, then ends up on a mysterious island after jumping into the ocean.

Out of nowhere, Motoko's sister appears and is ready to pass on the dojo. However, Motoko is still not quite as strong as her sister and when big sister finds out about this, she gives Motoko an ultimatum: Motoko must beat her sister or marry Keitaro!
