While I certainly agree that the ML is very bland I think it has been implied (based just on my interpretation of the encrypted mtls we get for this story) that ML never actually disliked the MC. Like he thought she was weird but not malicious and going by the flashbacks we get MC's antics due to her obsession is basically stalking (not saying stalking shouldn't be called out), ruining a couple of dresses and hairstyle and some mean words here and there. MC already had bad rumours surrounding her for no reason even before all these so the rumours we hear now might just be exaggerated than some MC actually did herself before her memory gain.
Though honestly as you and some others have mentioned, ML is so boring (and it's not because he is "nice", it's because he has no personality) and they barely have any chemistry together. Sasha has a more interesting personality and a better dynamic with the MC so maybe this story should forget the romance and go childcare all the way ?
You're right, the romance kinda feels forced that way.
I figured, he seems to feel uncomfortable with her stares and the things she had done but never outright told her he hates her or so o:
Idk if it gets better cause I only read 15 chapters but the ml feels so bland to me, like he doesn't have any personality. He knew the mc stalked him and you could see that he feels uncomfortable with that but just cause his nephew likes her he's just like "yeah she must be a good person, i dun care what she did a year ago, if my nephew says she's nice she must be nice" it's like the whole stalking didn't happen and he doesn't even feel the slightest bit uncomfortable or anything, he suddenly likes her cause she saved the child and thats it lmao could be just me but he's just bland and no personality whatsoever
