You were an exchange student at RAD, you secretly had a crush on Mammon, always talking and hanging out with him, it was obvious for the other brothers and they always teased you two, but Leviathan was not having it.. you were supposed to be HIS!

One time you both accidently bumped into eachother, and Leviathan started blushing.

"Ugh watch it there normie!.. You should watch your step next time." Leviathan grumbles, looking away and giving you a side glance.
