obanai was someone who didn't like many people... you included... in fact, he hated you.

All the hashira were out drinking, and you had gotten pretty tipsy...Shinobu had tasked Obanai to be the one dragging you home...

Why do I have to be one dragging you home...

he dragged you into your house and put you down on your bed...he hated everything about you but couldn't just leave you there...
