What a show! Five fully functional main leads with their heads screwed on straight!

PLOT:
Loved: - Intriguing and wonderfully complex plot.
- comedic but smart teamwork required to solve the mysteries.
- unpredictability
Points off: sometimes got a little too hard/boring to follow because of the vast amount of characters involved... I skipped around quite a bit (but that's mandatory for most cdramas IMO).

OTP:
Loved: - they were a practical, intellectual couple; neither knows how to fight.
- they complement each other
- No misunderstandings, long love triangles or separations.... just two characters in love.
Romance doesn't take center stage, so for rom-com fans, this is probably not the drama to invest your time in. However, even their tiniest interactions got me so excited.

FL is a lovely character. The writers managed to perfect that delicate balance— she's smart and skilled while also being innocent and sweet. She never got on my nerves for being too childish or stupid.

ML was very nice to all his subordinates from the get-go, even though he's aloof and tsundere-ish. I liked the fact that he was the one who kept overthinking their relationship. The actor really impressed me in one of his heightened-emotions scenes.

Supporting cast were all wonderful. Strong warrior men and women. Satisfactory Ending.
