The character here have no character development, the bad characters realized their mistakes and regret, that's all, and continue being bad until the end.

Everybody should have a 2nd chances despite being a bad person.

I think, everyone deserve to be happy including the villain, they just need some chances and the right guide.

The story would be better if the bad character become better, and in good terms with MC.

This is a case of golden child and scapegoat. They both are victims of their circumstances. I am so mad that she is being disregarded to this type of life by the Zhao family that "loved her so much". Their love is so shallow. How can you treat the child you raised for so many years like this? If you didn't want to keep a relationship you should at the very least settle a home for her. She is also a victim of you own s*upidity

They were in the wrong and they actually learn their lesson. They learned that they treated the real daughter super poorly. And they learn that relatively quickly (the brothers learned it way faster than their mother.) The lesson of "It's too late" was ironically, learned very late. THey keep on trying to win the MC back, but in a half-handed way until the very end.

Honestly, She's almost as innocent as the MC in most of the story. She was beloved to the family and never purposefully caused trouble until things started changing for the worst. In total, there are only 2 times where she goes 'hate-able'. One is legitimate and the other one is at the very end when she kinda goes crazy. Besides being jealous, she was getting a lot of unnecessary hate from the other characters "

1. There is a "point system" that rewards the MC for staying near and interacting with the "lucky people" to negate her "villain unluckiness". This creates the expectation that she will interact with multiple "love interests" and create some artificial drama. Long story short, not the case. She sticks with ML and keeps it that way.

2. There is a good chunk of the romantic story that never mentions the "point system". I found it to be very pleasing to see a romantic scene and not have the MC be like "Nice! 12 more points!". It really helped the flow of the romantic development be more natural and helps see the feeling between them as genuine

The family sometimes sob saying stuff like "If only we kicked out the adopted daughter" or, "Why did we choose the fake daughter?" and other things in the later chapters that I don't want to spoil. Point is, they blame the adopted daughter for clearly THEIR OWN TERRIBLE BEHAVIOR when they should be self-reflecting, instead of pointing fingers.
