I dont use much logic in reading this cause the story is obviously going for comedy rather than serious plot. I get it that the author use a lot of silly misunderstandings that can be clear up easily if they just talk properly but think about it how many people can think rationally and say what they wanted to say when theyre overwhelmed with emotions. Besides when did the story mentioned that the MC is smart in to begin with? Just because the mc transmigrated from the modern world that doesnt make them smarter than anyone else in the story.
He could have changed and start amends after he got in power. Also he didnt need to go out of his way to torment her; the father said not to love and ignore, if he was already planning to get another woman after marrying her then he shouldnt have consumated and got her pregnant then. Ignorance or deliberate, what he did is despicable.
Damn ignorant malicious humans in stories..!!
