I read somewhere that they aren't related at all, both the mother and father cheated (the mother with her assistant? And the father with a mistress) tengox
I thought the dad brought him from the orphanage because he was the illegitimate son cuz the dad cheated.
The ML isn't even related to her by blood! Okay phew. He's an orphan they brought in. And both of them have people reincarnated into them. Excitingggg
