I saw every episode of Love Hina subbed, and it was very entertaining. It's about a 20-year old loser named Keitaro who is a 2nd year ronin (meaning he failed to get into college after high school twice). Keitaro's grades are not good enough to get into Tokyo University, which is the only college he wants to get accepted to. When Keitaro was little, he promised to get into Tokyo U with a girl. She was the only girl that liked Keitaro, so he's dying to keep his promise and see her again...although he can't remember her name.
Keitaro's parents refuse to support him any longer, so he gets a job at his grandma's inn, which recently became an all-girls dormitory. Keitaro becomes the kanrinin (manager) and for the first time in his life, he is surrounded by women. The residents, ranging from a shy junior high girl to a sword wielding kendo master, either like or dislike Keitaro at first, but he soon gains their friendship, despite the fact they think he's a pervert and they kick the living crap out of him at least once each episode. There's also a romantic relationship that evolves between Keitaro and Naru, who deep inside really likes the guy (she kicks the most crap out of him, by the way).
Later in the series, a love triangle develops between Keitaro, Naru, and another girl...and she might be the girl from Keitaro's past! It's very funny and the story is interesting. If you liked the romance aspect of Tenchi Muyo!, I highly suggest Love Hina.
