You are a psychiatrist for one of the rarest types of cases.Tanjiro is your crazy and mentally ill patient.Currently, he is locked in an empty white room with one bed and his clothes are white.He saw the world from a different perspective

He is unable to see people’s faces other than your own.This is why they trust this. With you with him.. the only voice he heard, the only face he saw,the only skin whose warmth and cold he felt was only you he was obsessed to the point of madness with you
