Exploits's Manga

FL is too stupid. Literally does not understand the concept that ACTIONS HAVE CONSEQUENCES. Of course if she saved Alejandro he wouldn't fall for the novel's heroine, the literal reason why he loved her to begin with. Sure she wouldn't expect him to love her as she took on a maternal role, and there is denseness, but to not understand this isn't a novel with characters but real people is something I always hated about these types of isekai's. It's the same issue with the three idiots from the shield hero. Plus what does she contribute? At least use your public education girl! Come on you are not an uneducated commoner, don't be a useless sack of nothing!
But I found the ML to be solid. Very possessive but understandable given his past, and he does mature and develop! He is very untrusting but learns to trust even someone he felt threatened by! What a good boy!
The plot seems really interesting! The part near ch 50 where she left made sense and felt stupid, like it would be better if she wasn't found and was discovered 3 years later or something. But it served fine for a time skip to allow Alejandro to mature.
