First of all, I started and continued it because the cast appeared on running man.
But this drama has received a lot of negative response. Why? because first of all it is based on a questionable adult webtoon. Of course the drama is not going that way. But the female lead does get touchy with the male lead, who has a girlfriend, since the start. Plus in the first episodes she is a high schooler but is not your average student. She can be described as being a "bad boy" (but with the non-romanticized meaning of it). On the other hand the male lead is a real pushover, he doesn't seem to have much pride and does everything his girlfriend says and not only that he doesn't think much of the "touches" the female lead does. Any other would have taken advantage of it but kudos to choi dae hyun for not doing anything. Anyway he is quite an average male lead of an adult webtoon. lol There is also male lead's friend who is none other than an adult webtoon artist! It's quite rare in korean dramas so it had met a lot of controversy.

But once you go past the controversies and the image that source material may have left, this is just an average light-hearted romantic comedy, nothing more and nothing less. :) the western popular dramas are usually much more "adult" than this one.
Personally I really love strong and fighting people in dramas. So that was mostly what kept me watching. Saet Byul, our female heroine is extremely strong. to the point it gets ridiculous. lol So it's like a slapstick comedy with her beating up bad people. But later you get to know all the characters from a different perspective.
You get to know that ml is a thoughtful boyfriend, with quite a strong sense of justice. That fl lead is a child that had a lot in her life but thinks a lot about her friends and sister. Does everything to protect them and suites the ml much more. That the questionable ml's webtoon artist friend is actually really sensitive and can't draw adult scenes and his webtoon is just mostly romance. That ml's family may seem very "country bumpkin"-ish, but are very thoughtful, love each other a lot and stand strong for each other.
As this drama was made by the stuff who made Fiery Priest, it has a lot of funny references also.

So it's just an average light hearted (slapstick) romantic comedy. A bit draggy in the middle with funny ending. So 6 for me is the best i could give this lol :) And mostly because i really love fighting!

So If all the negative feedback is keeping you from watching this drama, and you fear it will be controversial and inappropriate just give it a try. It is not "adult" at all. And the characters also are not particularly strange.

I never rewatch dramas so i put a random number there. Music was not very special so i just put 6 there. For me there wasn't any character that was especially interesting so i didn't put 10 for acting. the whole story was also normal so i put 6 :) but this all doesn't mean it's bad. It's a an okay drama for me :)

So if you like romantic comedies you can give it a try :) and decide if you like it or not.
