The first time writing a review but I felt the need to write one because of all the negative comments.
I'll list some facts here that made me love this drama

What made it different from other Romcom:
1- Smooth romance without unnecessary breakups or misunderstandings between the main leads.
2- many romantic scenes, almost every ep after ep 8 and they are satisfactory, so wait for it and don't drop it
3- the main leads were clear about their feelings and didn't care about the people opinion
4- their feeling developed quickly without hesitation, non of them tried to avoid the relationship or deny it from the beginning to the end (for example the FL didn't get scared because the ML is from a higher level, and the ML didnt get scared that his family might oppose)
5- Very positive, which you is sth need when you are tired from everyday life, this drama will surely comfort you especially if you watched it before you sleep.
6- strangely the father didn't resist the relationship a lot and he quickly accepted
7- the OSTs are all amazing
8- it resemble a sweet and somehow realistic love story which everyone one dream to experience.
9- The trust and honesty between the main leads is amazing they depended on each others supported and loved each others despite the problems they faced throughout the drama.
( i really love how they didn't break up when their relation was revealed and also when the FL saw the ML with his potential fiancé, she believed him and didnt misunderstand)
10- again solving the problems easily was a positive point for the drama in my opinion because sometimes you get tired from how other dramas complicate each problem and spend many episodes it so this drama can be resting area for you.

But I have to say that I skipped some parts which were mostly about the father and the sister and their unnecessary problems, they really didn't add anything to the story.

So all in all, what I want to say is that when other people think that the simplicity of this drama is what made it bad i believe that it is exactly the opposite, the smooth happy and honest relationship and the sincere acting of the main leads made it a perfect choice for a comforting drama.
