I noticed something. The mc doesn't have any specialties at all maybe her endurance and energy is a good thing but she doesn't even had talents. This what makes her character dull. The story is good though, however from what I can see where's the story going to. The story is becoming cliche like adding a love rival in here. It destroys the uniqueness of the story. And the pacing is bad I feel like it's not the time yet to fall in love in each other. I don't know but it feels like the male lead is not really in love with mc but being forced with the story flow. It feels like the author just came up with the idea of putting another fiance in here to make them realize that they love each other then became officially a couple.
Well that's my opinion.
