I didn't fully enjoy this series. I was uncomfortable and anxious the whole second seaso. There was a lot of sugar coated toxicity and manipulation on JoJo's part towards both male leads.
I do commend how true to reality the show was. People have the right to chose who they love, even if they betray and hurt others in the process. And like in the Love Alarm ending, they can end up happy and others are forced to move on from the heartbreak. It's sad, unfair and wrong but it happens, quite often.
I love the actors though and I take consolation in knowing Sun-oh has a happier ending in Forecasting Love and Weather and Nevertheless.
