Love the game, the writing, the characters, the story. The slang legit doesn't bother me (I'm not a native speaker). The characters models are not super beautiful top models but it's good and refreshing. If you can't stand it, just go on your way, there are a lot of other games for you. If the MC says she's super beautiful (she's not, that's the point, but not ugly either even though it's subjective) it's because he's under the influence of her power
Love the daughter model, she's got a freaking cute smile and I like the banter with her father (MC)
