To be honest, I dislike Jojo's character. It's like she's playing the victim. When she and Sun-Oh got in the crash, she got "scared" that Sun-Oh wouldn't like her anymore. It's like saying "I don't want him to hurt me so I'll hurt him first." The shield was basically useless, as it made Sun-Oh heartbroken and Hye-Yeong happy? I feel like Sun-Oh's new girlfriend was his way to cope and forget Jojo. You can tell she could make him happy in the first season, but it wasn't the way Jojo did it. If Jojo was gonna end up with Hye-yeong, I feel like making him the male lead would have been better, and Sun-Oh as the second male lead. The Jojo and Hye-yeong ship doesn't make sense in my opinion. I feel like Sun-Oh and Jojo would be better, they showed great chemistry, but she pushed him away to protect her feelings when she knows Sun-Oh would never leave her since he was her dream girl. Then Jojo apologizes, and they both move on. That's pretty much the only thing I liked in Season 2.
