This series is definitely not the worst series I've ever had the misfortune of watching (cough, tharntype s1, cough), but although it was pretty good in the beginning, it quickly got a bit .. boring. I enjoyed the plot at the start, I liked how they presented it and how Kuea's feelings were presented. I felt like I understood him in a way. I liked Lian as well, but he was honestly an asshole most of the time. I understood the plot, but honestly, I couldn't even get through the last episode. I skimmed most of the last episodes to be completely honest. I mostly kept watching for Yi and Diao as well as Syn and Nuer rather than Kuea and Lian. It was the same thing each episode for Kuea and Lian, just constant lying even until the final episode. They brushed over their problems a lot, and nothing truly got resolved. Not much communication. It was unsatisfying, really. It just kept getting worse as the episodes furthered towards the end. They had their cute moments like the side couples, but overall their romance was a bit lackluster to me. I have to give them a huge plus for the music though, I absolutely adored the music in the series. NuNew seriously has a gorgeous voice, he did amazing with his singing for the series. I never skipped his singing moments and I still go back to watch him sing Change. I also really adored the cast, MaxNat have amazing chemistry (they're my favorite honestly) as well as ZeeNew and TutorYim. Their chemistry outside of the series is adorable and MaxNat's vlogs together are so sweet.
Overall, I wouldn't recommend this series but I'd definitely recommend listening to NuNew's music and watching other series that these actors are in instead.
