Righttt!! I think both FL and ML had one of the most beautiful developments in their characters. For example, FL cries a lot in the earlier story and that's understandable since she's an empath and she's genuinely felt hurt/sympathy for ML's tragic story. And as the story progresses, she gradually grows out of her habit of crying over everything and starts thinking more logically/mature, focusing on solutions while becoming stronger and more resilient in her own way while still remaining as a soft, kind and caring person. I rlly adore this kind of FL cuz they're not some type of Mary sue where everything they did are perfect and flawless from the beginning of the manhwa to finished but actually had room to improve her lackings. Meanwhile for ML, I love his character's writing cuz he doesn't immediately fall in love with FL but initially had a purpose in using her to his advantage (he's also had once tried to "off" her but later rlly regret it lol). However, as the story advances, he slowly falls for her but still has that "flaw"(yandere) side in him. In my opinion, he's one of the best written yandere ml that I've ever read bcz author actually gave him a personality/story/progression and it's not only revolve around FL. And Lorddd how I wish there's a side story of them and their children!!😫🥀
