This anime is one I've just completed watching over the last few weeks having bought it a while back.
It's in Funimations really cheap re-issue series called S.A.V.E and was not issued in it's entirety in the UK as ADV who had a license only issued the first three before hitting financial problems and dropped it.
The best way to describe this anime is really a slice of life school romantic comedy albeit one set around a track and field school club.
If you remember high school you just might recall relationship status and how to improve them figured a lot in your thoughts as well as peer popularity pressure.
Yamato has just moved in with his Auntie at an all girl bath house and he has fallen head over heels in love with Suzaka, the school's number one athlete. One problem - she hardly realizes he exists.
