I appreciate the storyline, particularly the captivating beginning. However, the initial part is a bit unsettling, with the twins' complex emotions towards each other, particularly the brother. My initial assumption was that the main character (ML) might be the reincarnation of the twin, which is disturbing, but let's set that aside.
The issue I have with this novel is the ML's behavior. Despite his dedication, there's a concerning vibe that he comes across as grooming, especially since the female lead (FL) tends to cling to him. Their age difference, being 20 and 14, may not be significant, but considering the FL's young age, it feels inappropriate at times. The transition from sibling relationship to something more intimate seems rushed and disregards the MC's feelings, which triggers discomfort in me. I can't help but empathize with the original FL's biological brother, who faces possessiveness from the ML, preventing him from interacting with his own sister.
If the ML hadn't become overly possessive after Chapter 80, I would've given the book a higher rating. Instead, his actions often verge on sexual harassment, making me dread his appearances. One scene in particular, where he shamelessly slaps the 14-year-old FL's butt, knowing full well her true age, is highly disturbing.
The author does excel in creating intriguing supporting characters, but their development is limited, focusing mainly on the FL's experiences and interactions. I wished to see more depth in their lives, especially those connected to the FL's fortune. The absence of significant secondary characters like the dragon-phoenix twins of the crown prince feels like a missed opportunity.
Overall, while the ML's descent adds a certain level of complexity, it's not entirely unpredictable. Taking a more objective view, I'd give the book a 4 out of 5 stars. It could've been higher, but the disturbing aspects and lack of focus on other characters prevent it from reaching its full potential.
