Sucked at first sight, actually. It certainly failed to leave a good first impression. The first episode was horrendous in all regards, especially when you get some context later on. Subsequently, this led to all kinds of problems with the narrative. At first, the story presented a big predicament to overcome, as described in the synopsis, what would ML do once he meet her again, but the drama decided to nullify the tension in a record time and turn the drama into a mindless slice of life with bubbly visuals. The unusual romance was never justified, the drama also attempted to play the same scenario for their romance at the end but it only made things worse by creating an unnecessary new diversion that came with it more problems, it just doesn't work unless one of them was mentally challenged. One of the drama's genres is mystery, but there was barely any and what was present was surface level cheap addition.
