this series was amazing, the suspense, mystery, and action kept it very interesting. The ultra-cute couple was amazing and added so much to the show. I loved the character arc of the main characters and especially liked how badass Jeong Hoo was, but at the same time, he was very cute!!!! loved ittt
ML was protective afff!. watching over her at night, spying, tells ppl to keep her safe when he can't. Fighting the bad guys so they don't hurt her, etc

Their families' backstory was also very interesting to watch and every single actor played his/her part to perfection
I recommend watching it.
