The beginning of this drama is so cheesy, I almost dropped it. The female lead falls into a romance novel and tries to break up the male lead and the girlfriend written for him in the story. This part was interesting on a "meta" level, playing with the tropes around the sweet, helpless romantic female lead and our aggressive protagonist's attempts to sabotage their relationship and take the ML for herself. But knowing it was a fictional world, her actions were over-the-top and often cringey and ridiculous. However the drama began to change for the better (in my opinion) as her relationship deepened with the ML and become more genuine. I'm not going to give details here because I want this review to remain spoiler-free, but there's a major plot twist between the fictional world and the real world, and it gives both the FL and ML the opportunity to act differently (and with more sincerity) as their relationship progresses. So even if you're a little wary at the beginning, I recommend sticking with this drama, it gets significantly better as it progresses and winds up as a genuinely entertaining and sweet romance.
