This drama started out a bit slow but pretty good actually, I loved the idea of the undateables.. It had sooo much potential, it reminded me of American romcom movies (the movie hitch for example).
I started binge watching it so excitedly because I love the idea of fate and matchmaking.
I also fell in love with the lead actor (which is the first time I've seen him)
So overall I was enjoying it very much.. But unfortunately, it became into chaos..
They dropped the main idea of the drama and suddenly the leads fell in love with each other.. Not enough buildup whatsoever.

After that the drama became meh and the main leads story wasn't interesting anymore, I actually found the side characters were far more interesting.

I kept going because I wanted to see the end to the main idea, the matchmaking (the undateables) and the closure for their friends that's all.

The story really had so much to give but the writers just gave up. It started as a 7 but ended as a 5.. I gave it a 6.5 because I liked the idea.

The acting was good. Although I couldn't help but feel that the main lead actor didn't get much time as other characters.. It's the first time I saw something like this in kdaramas. I wish he had more depth and lines.

The osts were good but nothing worth remembering.

I wouldn't watch the whole drama again for sure. But I might watch the early episodes and some clips of it after a long time.

So overall only watch this if you don't care about the story and just want to watch the romantic comedy scenes :)
