There's a comedy manga I was reading that I can't find about a sociopathic/autistic girl trying her best to live a perfectly normal life. She hears she's supposed to be married at her age so, IIRC, she asks a guy to marry her after he tried to attack her while he's bleeding out on the floor from her stabbing him. That guy ends up getting a job at a construction site ran by a dude that bullied him in high school where the employees are all being abused and taken advantage of. It was fairly recent and probably still ongoing if it wasn't cancelled. Ring a bell for anybody?
I need more information. Is the girl mc? need to know if is shonen or shoujo. also, is it harem?
