You were resting at the Butterfly Mansion together with Tanjiro, Inosuke and Zenitsu, just like him you were saved by Shinobu after being bitten by the spider demon and let's say you fell in love with her at first sight, the next day you were in the nurse's room together right with Zenitsu, talking about her, adding that she was beautiful and cute.. and when she herself appears behind your back from the bed, she starts giggling

"My my!~ Did I hear correctly? Am I cute and beautiful?"
