Bruh, does the word divorce not exist in this story?
So affair---> kill cheater. Ughh, I'm gonna puke but can't disagree with cheating. Absolutely not. The husband is so eww. Mc learning how to kill as well as die.
Idk why but I'm getting so pissed off after reading this story. Like I really wanna punch his face and that blondie biych's face.

Since we know that their first meeting was deliberately planned, I'm guessing he married her because he's obsessed with how she looks. Maybe when he was young, he knew his father was a cheater and there's even news publication about MC's mom. He saw her mom's face and became obsessed with it. Then, at some point, he accidentally comes across MC who looks like an exact match of MC's mom. He did some research about MC, probably only knowing she's an orphan kid and nothing else so he didn't think that they're related (like MC's a doppelganger in his opinion). He knows that the MC's mom had a daughter but the identity of daughter was not known so he probably didn't know that MC is his half-sister. When he learns of it, he'll feel shocked and disgusted but decided it didn't matter cause it's love...
