I actually kind of like that they didn't end up together (at least for now, maybe in the side stories they will) but the fact that even though she fell in love with him, she still stuck with her main goal of betraying him to escape. Sometimes manwhas derail once the mc falls in love but I'm glad this one didn't, because even if she did kill that piece of shit, she doesn't deserve to be in jail!
She doesn't look chubby she just looks like a child honestly. She's cute but doesn't look more than 12. The story was okay but overall too fast and had very one note characters. The story idea was good but feels like it was supposed to be a one shot that got dragged out to 18 chapters.
