reset 開端 ~ li shi qing 李詩情 : she was too impulsive and did stupid things that wasted time. you'd think that resetting the most times, she'd know better.
Unkind Ladies - the adult granddaughter. She was awfully dumb for someone who was a university professor (didn't even seem book smart). More than that, though, I couldn't figure out why two very eligible men were smitten with her.
yoo yeon-ju in Backstreet Rookie. She was just unnapreciative of everything in the relationship. When she cheated on him she had the audacity to be angry at him for no reason in particular. And after they broke up she was more involved in Dae Hyeons life than when they were together. That character was just a nuisance and very intrusive. Props to the amazing actress though. ;)
