This is the worst "I fell in love with the organ recipient from my deceased lover" type of drama. They pushed the subject of "cellular memory" way too far, making the girl a clone of the donor. The fact that Kam Woo Sung looks older than his real age and Choi Soo Young looks younger than her real age, made the entire thing worse than it already was. The relationship was too iffy regardless of that. I watched four dramas from the same writer and it seems she has a consistent record in fucking up the later parts of her projects. Good to know.
