For me this show is two parts, first 12 episodes and then the rest. I thought the first 12 were amazing, attention grapping and full of twists and turns but then the show goes into the conclusion parts and ends up dragging along, especially for binge-watchers like me cause of the flashbacks and repetition. But good news is that it doesn't take away from the show that much. If you like murder mystery/thriller shows this is a 100% must watch with amazing casting and great chemistry between the characters, and the amount of times it pulled a SURPRISE PLOT TWIST was peak K-Drama standards. I really liked it, now I must make some egg tarts and hope my childs ends up like Eun Ha.
