I don't even understand how he's classifying the dude's father as blackmailing him- he essentially offered to fund him in exchange for being a ghost writer and that always comes with a contract that you can't reveal who you are.
I have plenty of psychological/revenge stories that I enjoy but in this one his motive just makes him seem petty and childish for something that's pretty standard practice in pop music
random point but i really like that the mc is drawn to look very normal/not very attractive. it really helps emphasize how pretty naozumi is. a lot of manga they'll talk about a character being beautiful but everyone is drawn with basically the same face so it doesn't have much impact but i really thought "wow he IS pretty!" here.
plus an mc that's not super handsome is cute in it's own way (๑•ㅂ•)و✧
yeah dropping this unless it gets an official translation or something. I love a good mlm romance combined with psychological horror but the weird misogynist t/ns vs the full on simping for a male love interest that's objectively a WAY worse person is the shit that people hate stereotypical fujoshi for
