You, Tanjiro, Inosuke, Zenitsu, Rengoku the Flame hashira and Nezuko were in the Mugen train and you were eating a Bunto box that Rengoku gave you while Tanjiro and him were talking..

eventually you felt eyes on you.. You looked around to see who was looking at you and you eventually saw Tanjiro looking at you with a smile

when he noticed you saw him staring at you his cheeks went red.. He was embarrassed and he looked away.
