I want to start off with positive points, yeah it does have few positive things that I wanna mention, lol.
1) first season couple's cameo, loved that scene.
2) I really liked how FL's mom was super rich, strong, pretty and smart all in one..cuz in most of the dramas it's other way round. She was the highlight of this show and all her scenes were super entertaining, I never skipped her scenes. Her acting was pretty good.
3) ML - he is cute, considerate, kind and everything. Acting was good.
4) actors acting was good, those 3 stars are for their acting.

Now negative points. There are many but I will mention only few that made be give only 3 stars.
1) FL- I guess her character was supposed to be cute and innocent cuz of the way she was brought up in mangolia but I found her very annoying. It wasn't cute in anyway her constant smiling for no reason and making faces trying to be cute was very irritating. (Am talking about character not actress)

2) villain is handsome and looked dangerous in the beginning but he was actually very stupid, mentally and emotionally weak not to mention how it ended with him committing suicide. I feel pity for him but for God sake hez a villain and took many innocent lives, distributed drugs etc. here I don't really understand what writer was trying to do cuz his pitiful story and everything made many people actually hate FL for betraying him, leaving them in confusion on whether he really deserved to die or not, and suicide? Really? Left everyone with bitter taste by the end, maybe that's what writers were trying to do but it made villain's character steal the focus from main leads and I didn't really bother about leads cuz villain's character had more depth than leads only cuz of his past lol cuz he isn't that smart there are many points where you feel hez soo dumb, he was played with for more than half of the story. anyways it's really silly how writers tried to make us LOVE AND HATE him at the same time but what really happened was that it made us get annoyed with FL even more for God sake show's title is on FL but her character itself is very annoying. and she did betray him no matter what the 'reason' was everything eventually led him to commit suicide. At least they should have shown him getting arrested or something. There's no going back as his life is anyways ruined cuz of all the wrong decisions he made but committing suicide brought even more sympathy to his character. Like why?

3) story - Gosh!! Didn't like the whole drug shit at all. There was no solid story. Even though its on a sensitive topic (drugs) but story wasn't good at all. I didn't enjoy it.
