I decided to write a review after reading contradictory comments and reviews about this show.

First of all, I don't think young people - let's say younger than 25 - would really appreciate this drama at its full value.
Of course, we are all entitled to an opinion, but one shouldn't judge life situations one couldn't have lived.
(And yes, I'm over 30, been there, done that, I know what I'm talking about. ;) Or?...)

I think this drama is about couples and growth and it has a very original take on it.
We have the cute couple, the bickering on/off couple, the shy one, the gay couple and the complicated one. We also have couples where one is more into it than the other, "friends with benefits" etc.

If you had several relationships in your life, you'll probably recognize some of the situations: being intimate with someone you like but not love, having someone nice liking/loving you but you can't reciprocate, not knowing how to go from friends to lovers or the opposite.
Relationships may evolve, if you started with a carefree spending time together you may want more - or not.

And this is all this drama is about. Young people living their experiences, more or less mature, growing in a little better person after this.
I don't think any of them is good or bad or stupid like I saw in some comments. Just normal, perhaps with flaws but also good parts.

BTW, a special mention for the same sex couple (for once they are girls) - it was integrated so seamlessly in the story, so natural that I'd give a special point only for this.

I also appreciated the normal, natural behaviour of young people in this drama - PDA like holding hands, hugging etc. weren't made to seem inappropriate like they are in most kdramas. It has a "western" and modern vibe.

I found the actors were good in expressing the different emotions they went through.
OST is nice, I even added the main song to one of my playlists.

Rewatch value - I gave it a 9, I definitely watch it again after some time.

In conclusion, definitely go for it but, if you're young, instead of judging it harshly, tell yourself that perhaps you haven't experienced some of the situations they go through.
