Anime (romancy comedy) series suggestions...?

I can't believe no one's mentioned Miracle Train, which is my fav romantic comedy in years. Basically: there is a magical train in the Tokyo subway system which is ridden by a crew of gorgeous guys--each of whom is a personification of one of the stations on the route, sort-of the station's soul--and no one can board this train except a female passenger with a problem. Once she is aboard, she can't leave the Miracle Train until the stations have figured out her problem and solved it. --The problems aren't all romantic ones, but I'd still call it a romance-comedy, and it's just totally sweet. I loved it. =)
