I recommend this manhwa if you are into slow burns and have 240 chapters to spare. I suggest taking the other reviews of this manhwa with a grain of salt, as they were likely fatigued by the manhwa's pacing. (I know because I wanted to see people's reactions in the comments, and it was them complaining how the manhwa still wasn't over at the time). I personally binged the whole thing, so my experience was very much streamlined, and I got the entire plot versus waiting weekly for chapters to drop. A big point of contention is that the main character stayed a child for toolong. I am okay with this because it made the time transitions much less jarring; I'd rather have this than what some other manwhas do, which is time changing mid-chapter without much of a transition. In addition, the first 80-90 or so chapters genuinely feel very short compared to many manhwa chapters (I'd estimate ~60% the length).

Another point of contention is that the main character is an "idol". Personally, this is the first time I have encountered a plot point where the MC uses fame as a shield against people who would try to do her harm.

Also, the claims about the harem are a bit overstated. Yes, the characters exist, and they mainly appear when the main character is a child. Once she becomes a teenager, the story focuses more on the male lead. The previous characters still appear sporadically (probably for fanservice for the audience in the case of Harrison), and there is a tension between the male lead and his best friend.
