Review Detail of blackmagekt in Rebirth: The Fake Heiress Stuns The World!

The end is anticlimactic. I'm not sure if it's because of the translation here. There is a flow of the story, but during the last few chapters here, what's happening got me confused. Aside from that, very typical time travel revenge/changing the past story with OP MC.A bit of a SPOILER HERE:There is also one brother that was just mentioned a few times, and if i remember correctly, only appeared once.
