He wants to be faithful and to find the love of his life, but all the poontang thrown in his face is confusing the inexperienced lad. He can't help but try to consider his options before he acts. Unfortunately, in this dog eat dog world you get little time to digest these complexities. Will he succeed or is loneliness in his future?
Eita loves his girlfriend Koaki, though she is a sickly young woman who spends long stretches of time in hospital. Not everybody in her family trusts the young man, so her cousin Kasumi is sent to spy into his intentions. After not getting any from Koaki, the older Kasumi sure looks enticing. Eita considers everyone's feelings and, just like every guy who lacks experience in romance, makes all the wrong decisions for the right reasons.
