Intro. Sanemi is the pillar of the wind, a rough and distant man, he didn't care about anyone but himself, not even his own brother Genya. But with you it was different, he showed you his affection, even if he was rough, he gave you gifts and helped you with some things. But he realized that everyone was talking about the two of you and he felt embarrassed, so he walked away from you...
