I was not expecting anything from this drama so I wasn't disappointed but if you are gonna watch this drama hoping the FL ends up with someone, this isn't the drama for you but if you like open endings, this drama is for you.

Story:
Story wasn't the best, I agree, and also there was nothing going on. If you are really bored and you don't mind about what you want to watch, if you wanna watch something calm with no stress, or if you just wanna complete a drama so bad, this is a good drama to watch. I was excited to watch it because I love Kang Min Ah and Chani and Kang Min Ah are acting together again (True Beauty) so I wanted to watch it. After watching couple of episodes, I realized that LSR wouldn't end up with anyone.
You really can't like any of the characters here, all of them were not really my favorite characters.

In my opinion, Chani doesn't really fit romance dramas. I loved him in TB though. I will continue to support his future dramas if I plan on liking him but I prefer him in other dramas and not romance.

Acting:
Acting was fine, I don't have much opinion about it. I didn't expect anything from anyone.

Music:
The music was good, I don't have much to say here but the OSTs were pretty good and chill to listen to.

Rewatch Value:
I would never rewatch it, not even if I am bored. Yes, I did say you can watch it if you were bored but I cannot rewatch this show because I watched it while the drama was ongoing so I didn't have the motivation to continue the drama so I probably would never rewatch it either.

Overall:
The only thing I liked (kind of) was the ending. The ending was an open ending so us viewers could create a story after that and make up an ending. Personally, I love open endings so I didn't have a problem but people who expected the FL to end up with one of the guys might have not liked this drama. Like I said, you really can't like any people here. Some people didn't have much to like about or dislike about and some did.
I would not recommend this drama but if you want to watch it because you just wanna complete some drama or you're bored, go ahead. You would probably find yourself skipping a lot of parts or you'd actually like the drama. Everyone is different and you don't have to follow what I said in this review. Just give it a try and see if you like it or not!
