Tomo Aizawa is a tomboy who has been head-over-heels in love with her childhood friend Junichirou Kubota for a long time, even though he doesn't actually love her and only sees her as "one of the boys". Hilarity ensues when she tries many times in vain to show her love, but ends up getting physical at times. Additionally, their mutual friend Misuzu Gundou does things her way. Others are also mixed in the mess.
