I wouldn’t suggest to try to connect the events from season 1 because it will only give headaches and inconsistencies. But to watch the drama forgetting most of the important things from GGS1. Personally I enjoyed more GGS1, the competitions, romances, characters, bromance, family dynamics, teamwork had greater impact on me than GGS2. I could see myself watching GGS1 again but I can’t bring myself to rewatch GGS2. I forced myself to finish for the main actor, i became his fan from A Love So Beautiful.
