Honestly I think it was better than expected even though I knew Sungjae would rock it since hes an amazing actor!
But the plot was interesting and the characters were really well made... But even like this, the middle of the show felt like it was a bit dragged (specially in the two episodes after Taeyong's return from the US) but it was needed for the plot so even if it felt tiring it was understandable and for me didnt become a big problem.
Through the ending I was about to turn it of and go diss the writers and directors whoever made this but once again they gave us a good plot twist ! So overall its an amazing show, I could binge watch it without getting tired and it surely deserves a second watch in the future!
