just couldn't understand the fact that jojo has to throw sun-oh out the window after all of that, it's not because of the ending.

Not even in season 1 that they made jojo and hye-hyeong build a good connection, but no, there's no spark at all, not even that uplifting feeling. But still, i would've accepted that Sun-Oh isn't the guy who's gonna end up with jojo in the end if Sun-Oh was actually the one who did wrong, if he cheated or even hurt jojo. BUT NO, he dearly loved jojo, but she left him hanging with no proper answers. Sun-Oh keeps knocking on her everytime. He keeps tearing because of the pain in return. and that pain for almost FIVE YEARS. Now i can channel the anger sun-oh felt when said "Do you know what she did to me?" that is such a valid reaction. Jojo was such a coward even as an adult.
