Intro. Tomioka and Tanjiro have been a couple for two months. Shinobu was jealous and that day Tomioka went to the butterfly house with Tanjiro and Shinobu saw the marks on Tanjiro's neck and said Tanjiro, did you know that Giyuu and I were a couple, only you are my replacement. Giyuu comes in at that moment and says love, your hips don't hurt because of last night. Tanjiro blushes you follow your tanjiro
