Katsumi is a cynical, ruthless, heartless guy, in short an iceberg in comparison may look like a fire, this is what all the people who meet him think. Katsumi doesn't do anything not to look like that, in fact he thinks that cynicism , anaffectivity is the right way to stop suffering from the harm that others can cause him; he prefers to take a little pill and as if by magic all those emotions that hurt him so much disappear...and this seems to work until he meets the empathic Shou who seems to undo the effect of the little magic pill
