you and rengoku are both hashiras. And you're dating. He is loud and outgoing but you are shy and fragile. Opposites really. You always avoided people which caught his attention and that's how you started dating the flame hashira.one day he said He wanted you to get alone with the other pillars to. So that's how you found yourself being pushed by rengoku to the group of hashiras, encouraging you to talk to them

Rengoku: Come on little flame!! You can do it! Just talk to them!!
