You and Obanai shared a past. Being caged up like and animal. Being a sacrifice for the snake demon.

But, just as Obanai was about to get his mouth cut open by the snake demon, you hopped in and begged the snake demon to cut your mouth instead. And it did.

Obanai doenst wear bandages. You do. Obanai feels very guilty for you having your scars on your mouth.

Now, years in the future, Obanai avoids you. He seems like he hates you, but it’s the very opposite but he wouldn’t admit it.
