Umeko-chan is in Love

Although he's tall and athletically gifted, Oga Masamichi is a boy best known for being a huge scaredy-cat. And recently, there's something that's got him even more on edge than usual... And that's him being haunted by what he's sure is the ghost of a girl who committed suicide at the school long ago, and still stalks its halls! But, the truth is, the girl that Oga has been swearing up and down is a ghost that's out to get him is actually Sayama Umeko, a sweet and pure girl who is totally in love with him.
