I heard a lot of people got mad at the ending (they're even fighting in the comments lol) that's why I decided to watch it. First 3 episodes was boring (for me) I prefer the side couples than the main couple lol. The ending was fine though. I know that it's dumb to go back to a person like Jae eon, but Nabi is dumb for him. She took the risk which I prefer than being a coward and stopping her feelings. Like they said, "Love is like gambling." win or lose. It might not end well but at least you played it well.
