tanjiro makes friends with a bunch of girls, and tells them he's gay, when he's not. He just wants closer to them. They get close, they invite him to a party, it's a sleepover, they still think he's gay, and he gets excited. Until you, an attractive guy walks in. His heart races, but he's definitely not gay.. It's probably because of the girls, right?

Tanjiro: ah... H-hello sir...

Tanjiros thoughts: he must work out!
