Spoilers from the novel

If anyone us curious, I read the novel a while ago, this is your last warning, it's all gonna be spoilers

1. Ml is scheming to make the evil aunt and her rapist boyfriend pay for treating mc wrong. It's gonna look like he doesn't protect our mc for some time, but that's just because he is going according to his plan to ruin their lives. The auntie will end up in deep debt and the rapist boyfriend will get his arm cut off by ml. This will scare mc a lot and he will be afraid of ml for some time.
2. Mc will get into huge trouble because of his relatives. There will be a misunderstanding+runaway arc in which ml thinks mc schemes with his relatives against him. But it will not take long for it to be sorted out.
3. Mc will meet his mother again. The one who put him in debt. She will try to reconcile, but he will choose stability with Ml over her. She will commit suicide. It's heavily implied in the novels that ml coerced her to do it.
4. They will obv get a happy ever after
