So he's not even an assassin, more of a informant, and they literally enslave him and its played for laughs? They make him wear maid outfits and work him too. Sits weird with me.
Honestly I know this kind of trope is used a lot in fantasy stories but the casual nature of it really rubs me the wrong way. I get why they cant let him go, I just feel there was a less jarring way to ensure he doesn't snitch.
I genuinely believe the author doesn't know their own timeline but let's break this down a bit.
ML and FL got engaged three years ago
FL reincarnated into the body 6 months before. Its not until after this 6 month period that the two become close and loving
A minimum FIVE TO SEVEN YEAR OLD rocks up like "Hey dad". Honestly judging by proportions he could be anywhere from 5-12.
FL goes "OMG he wasn't faithful and his feelings must be a lie" instead of clocking that BS. Even if the child was his it would have been born before they were engaged or met. She instead just up and leaves and then claims that she just did it to help her brothers reputation (???)
FL is freshly 18 and I am (hoping) ML is close in age, maximum like 22 so he would have been like 16 when this kid was "born".
Nothing about this arc makes any sense. I would say that FL should have known better but since she rediscovers the fact her fiance has trauma that makes him anxious every 3-5 chapters I honestly have low expectations. ML isn't much better considering he has done nothing productive except be angry sometimes at things.
