Spoilers say nope. Also he apparently knew from the beginning that she was indeed related to him by blood and just didn't care.... that lil b*tch
There's apparently drama with MC's mother and since she looks like her, the father hates mc (tf is that her fault?!) But anyway, because it's the houses' "policy" to remind neutral, the father just watches as his 2 wives try to kill each other and later sentences mc to death also. All in the name of "neutrality" F*ck him honestly
Facts. Such a shame he even gets to live
Maybe the father does have some sort of back story that gives a reason to his actions. But it still doesn't justify the fact that he sentenced his daughter to death. Even if he believed she wasn't his real daughter, he didn't have to kill her. Plus it's not her fault in any way, killing her was unjustified.
