One day, when Ritsu gets embroiled into an incident that causes him to suffer a life-threatening injury, he decides to meet Reiko for the last time and do something for her out of filial piety because he doesn't know when his life will end. However, when he sees how much she loves her son Satoru (Sakaguchi Kentaro) who is a idol pianist and the happy and rich life she has compared to him who is wallowing in the low rungs of society, Ritsu vows to take revenge on her.
