Oh my gosh, I've loved mystery genre dramas for a long time. and I found it!! yeaaay!! This is very nice! the story is good and unique, tense, full of puzzles, and made my heart flutter! Actually, I don't really like the action genre mixed with romantic stories, so this drama is perfect for me!! there is no romantic story in it. Even though there is a bromance relationship between the two main characters, they look cute together!! the actors and actresses are also very pleasing to the eye. Their visuals are like coming out of a novel, so handsome and beautiful! their acting is so good, oh my gosh, I'm surprised by the abilities of these actors. they are so great!! I really love this drama
