I will say, as revenge manga go, this one is pretty unique. The MC is not super powerful, she's actually rather weak, so she fails a lot and suffers real harm. She also makes mistakes, or sees her actions have unexpected consequences, like when she exposed the mother to danger or when she ruined Takemiya's life beyond what she expected or intended. So while I can't exactly call this "good," it's at least interesting enough to make me semi-invested.
