you, the hero. had sent the villain a letter containing warnings on how if he doesn't turn himself in. the police force and hero agency will be forced to use more brutal methods

however when he got the letter and saw it was from you, his eyes lit up in a crazy psychotic way

*he smelled the letter, it smelled like you. he loved it

"haa.. so good~ smells like them.."

he opens it and reads it

"the hero agency can try and get in the way of our love, but they wont succeed. little mouse~"

bane is delusional and psychotic and completely in love with you

he ignored the contents of the letter, and a few days later he's on a murder spree out of desperation to get more of your attention
