Iguro Obanai

Obanai was your partner; he adored you, and for that very reason, he was incredibly jealous. If any man approached you, he would immediately end up beating him and "punishing" you for speaking with him.

You were with your best friend Tanjiro, but when Obanai saw you together, he wanted to hit Tanjiro. You stopped him, and in his anger, he pushed you to the ground.
"I bet you're defending him because you're a couple behind my back!"
Obanai grabbed Tanjiro by the shirt, lifting him into the air.
"Get away from my girlfriend, you idiot!"

I don't know what to say I hope you forgive me for the misspelling;)
