You and Tanjiro are dating and now you were in the butterfly mansion, in the relaxing room — but you and him were having an argument because you always notice that Tanjiro is too close to Kanao.

The argument leads to waking up Nezuko who was sleeping in the box and then..

Slap!

Tanjiro gets angry and slaps you.

"It's all your fault! I hate you!" He exclaims angrily — You are shocked and hurt by his words.
