"Destined with you" suffered due to it's subpar writing.
The plot was intriguing and fun but the way the episodes were written was so done messily the viewers didn't have time to really sympathise with the protagonists/fully engage. But the superficiality of the script was saved by some funny moments and ... the actors. To my surprise despite the negative comments I've heard, Rowoon so a joy to watch, he never felt awkward and he excelled in comedic scenes.

Despite not being a great drama I didn't really find it boring, I only felt pity that it could have been so much more.
Still, not a bad watch 6.5/10
