I'll be honest, I'm a Wanjaai so I watched this series with high expectations. I am not totally disappointed, but I am absolutely not satisfied. I remember while it was airing, everyone was bashing the director for weird camera angles, lighting problems, and random cuts, but I'll be honest all these can be digested well if the script is superb.
This series had top-notch cast, Mew and Gulf's acting apart, the other cast were very good too. It has the best main CP with chemistry that can light up the sun. The OST's and music are good too.
But what it lacked was a good script and good pace. P'Mame wrote a script that made me think that maybe the author herself doesn't love her character anymore. They changed a lot of things from the actual novel and well some things were problematic in the story so I'm glad they did. But it felt like the whole season just needed ep 9-12; anything before that was unnecessary and doesn't add up to the main plot anyway.
But if you enjoyed TTS1, bet you'll watch it again. I'm giving it a 9.5 just because of MewGulf. So if you have watched TTS1 and wanna see some steamy hot kisses, awesome chemistry, superb acting from MC's, lovely and fluffy romance, eye candy guys, a bit toxic turn of events, unnecessary drama, bad script being pulled off by superb couple yada yada then go for it.
