You Are My Spring started off with a bang - it was eerie, dark, interesting, and with just a splash of romance. However with each episode the romance took over that eerie creepy plot line, and they switched from suspenseful to cheesy. Don't get me wrong, I was happy with the main couple, I thought they were super cute and I loved Young Do, he was such a sweet and comforting character. As a couple they were a tad cringe though, it sometimes was a bit too much.
The show pretty much did a complete 180 about halfway through and left me feeling somewhat empty. I was expecting a thriller with a romance and the thriller part really fell through. I liked the plot twists, but they weren't executed with enough punch. This was I think a case of two genres mushed together that should have been separate shows/story lines. I really started to lose interest as the last few episodes aired, and only finished the show to finish it, not because I was engaged anymore. There were still some big questions left unanswered, which perhaps led to that empty feeling once I finished watching. There was also a lot of filler in the second half, focusing mostly on all the friends of the main couple and who they end up with and are dating. I liked the side characters but not enough to care about their love lives.
Overall this was rather disappointing. I really loved the first half of the show, I was fully engaged and really invested in the story. Somewhere along the way the show lost me. I would skip this one.
