OK so lets start

The story :

WOW I did not expect that. So many ups and downs and what is even happing ? But overall ok.
The biggest issue was that the characters didn't make the slightest bit of sense.

Negative points :
SO spoiler warning again !!!
He is a literal 5 year old. He never not once tries to see anything in the perspective of another person. He goes around hurting, mistrusting, being mean, being terrible to others especially her and his dad. And when they then in return not 100 % trust and love him, he gets upset. And runs away to do more terrible things.
She was as forgiving and dumb as you can get. Don't get me wrong I liked her character but come on. Her husband brings a mistress home and her reaction is to be mad for like an hour ???????
He does whatever he wants and hurts so many people. I don't get why anybody would want to be with him or love him.
I would kick him to the curb right away :)
He cheats on her in front of her !!!!! And then gets mad when she wants a divorce ! Like what ?

Apart from that what was the dad character thinking in the beginning. He never tried to understand his sons hurt feelings and later on he completely changed and started to do all these super nice things ?

One other thing I didn't like was the reason for his revenge just doesn't make sense! I mean yeah sure his dad didn't pay much attention to his mom and left her on the wedding night ! Omg so what ! That was like 20 years ago and his mom and the other women are both dead! SO WHAT IS HE ON ABOUT ?

She would have so many better reasons for a revenge ! But nooooo she just forgives her dad for leaving her for the last 20 years and forgives him for kind of killing her mom ! Im serious ! I don't get her at all !

Let me add one more thing there isn't really an antagonist since our main is pretty terrible but like what are his friends ? They support him but never really criticize him for his bad and terrible life style ! .
And in the end one friend tries to kill the other and the decides oh not today and then they are friends again .... it just doesn't make sense. Expect for her and her friend there aren't any normal thinking people in this drama.

Safe :

The thing that saved this drama for me was my boredom and the chemistry and the acting :) I liked how he and her portrayed their characters and in opinion their scenes together were just too cute not to continue watching :)

So if aren't looking for something too serious and are pretty bored :) Then you can watch two people fall in love in this drama :)
