Kouta is unsure what to expect when his brother, Tetsuro comes back home after 6 years in Tokyo. But slowly memories of the childhood when they were close resurface together with the reason why Tetsuro left. Nothing new, but it is done well and the dialogues are quite logical. Their characters and slight quirks are also quite enjoyable. I get the vibe that Tetsuro is a bit of a sadist who likes teasing Kouta.
