Another Miss Oh

As we say in the book community, I'm DNFing this one. I just found both lead characters to be very unlikable people and impossible to root for. After 13 episodes, they were both still selfish, self-centered and cowardly, and I couldn't help but find them very toxic together (and it was complete BS to throw some sob-story 3/4 of the way in just to make your character seem a little more sympathetic) For a good chunk I found the older sister to be incredibly annoying , exasperating and ridiculous, but she eventually grew on me. Her and the ex-fiance were the only characters I liked, but I just couldn't endure over 5 more hours of torture to just get a few glimpses of them and find out how their arcs concluded (I have my guesses, but if anyone feels inclined to comment a few spoilers down below, I won't be mad). I just honestly can't see how this drama has such a high rating.
