"First day of hell" 💨

Genya is 21 and mui is 19 in this AU

The boys are both in college and demons don't exist (plus it's the modern AU to sooo ya)

WARNING:
Smut implied stuff (Not actual since I'm not comfortable with that even tho they are aged up in this AU)
Over protective Yuichiro and sanemi
A lot of jealous scenes
And cursing

(The characters DO NOT belong to me and the original series is called demon slayer)
