Many people are not happy with the ending which I don't object. But it's a drama you can not expect 100% satisfaction from a TV series.
What I LIKED : I liked how rara was a naive kid of a rich family who couldn't do anything alone except driving. She did not have any kind of reality check of the outside world but after the bankruptcy, she developed herself into a hardworking woman who is still that naive girl. I think writers have done an amazing job of keeping her innocence as it is and developing her othersides.
I liked the Male lead. Being a high schooler and this much maturity. I think the Male lead has impressed me the most.

What I had hard time accepting: Yeah I liked and loved the drama and ending but it's also true that the male lead could have told her the truth instead of saying "he is dead" . But then also every relationship has its own color and so does every person. So I don't have any complaint.
