My favorite thing was the ML, I loved everything about him. It was such a different kind of ML, it was absolutely refreshing.

I also loved a lot of relationships the FL had or built throughout the drama. That's the core of the story and what makes it alluring, in my opinion, so if you don't like stories that center on the relationships of its characters, then this isn't for you.

The only flaw it's some parts of the script.
There were things that were dragged that were unnecessary and a beautiful relationship with so much potential was destroyed and not treated properly which was the utmost shame (I'm not talking about a romantic relationship). They tried to fix it at the end, but they rushed it. In my opinion, it was really cliché how it was destroyed and it took from the story more than it brought. I wish the writer had made another choice, it would have been more interesting and heartwarming and much more in character.

Also, I would say that not every mother is the kind of mother this drama talks about. I get that in this case they are talking about mothers that are that way, but in the world there are plenty of women who shouldn't have been mothers.
