@Pach he is doing that because he never loved her. He loved her sister but his mother in law forced him to marry the older sister. Is it wrong that he is now going all lovely-dovely for his first and only love? no, it is not. He has the right to be happy. Is he wrong for doing it in this way? yes, he is very much in the wrong. He should divorce his first wife and leave her with good compensation for the hardship she went thru because he was cheating with her sister.
I truly hate the MC's mother. She knows her husband is a cheater and still try to act like that. I am sorry but that betray should have killed you if you are extremely emotional or make you bitter and jealous. If you have a daughter helping you and giving you hints that she is there to help you, you would do it. I am sorry but the MC's mother is not realistic and that is what is pissing me off. Shoujo's authors always look for a way to make the story continue with dumbass reasons. We have the MC no liking the general but respect him but the author is looking for ways for her to fall in love with him. He has been stalking her, he has been threatening her, he has been trying to " help her just to gain some insight, but he hasn't done anything good for her as a friend or a person who want to get to know her because he is attracted to/like her. Since he got nothing from her, he left knowing how capable she is.
Just because he is handsome, the author is saying little girl and teenagers will fall for it [ since shoujo is directed for pre-pubescent and teenagers]. The authors are giving a bad example to young readers and people wonder where young people get their ideas from.
I like the young general in the beginning, but the way he developed by the author is terrible. Yes, he helped her once or twice but only for him to get closer to her to find some info. A regular person without a love interest would do the same. It is more logical to think that he wouldn't do something so dumb and obvious if he is interested in her.
