Oh lord, so far, with 96 chapters in, this made me cry/tear up at least 3 times (do note that i was listening to golden hour - Fujii Kaze remix on loop as I was reading this manhwa) - you could almost think of it as a handbook for how to evenly give attention to your kids as a stepmom. The art is pretty. I would rate it around 8/10. One thing that I might nitpick is the fact that they give "bigger" noses to the stepsisters to make it seem as if they are "unattractive". But I guess it's hard to make a characterlook unattractive without giving them the typical snobby look.
Yes, it's an isekai/reincarnation manga, again. On one hand, it's always nice whenever there is world building and what not, but it doesn't push the fact that the stepmother is reincarnated, and focuses more on how she tries to be a good parent to the three girls. The events that happen as she does try do so is overall very wholesome. In some scenes, she expresses her thoughts in such an efficient way that she is now like a "model mother" for me lol
Of course, there is a bit of drama to get things going, but I don't think the manhwa will suddenly become tragic after this many chapters. So there is very little to no chance of accidentally torturing yourself with this one.
