It doesn't matter if you're new to Cdramas or BLs. the only warning i can give you is your life will change forever after the untamed.
it's worth your time and every second of the series is worth rewatching. the acting , chemistry between actors , visuals , OST, storyline , directing and literally EVERYTHING is the best of all times.
i keep watching it and it doesn't get boring even after 100th time.
if you're a big fan of yaoi and bl don't hesitate watching it. there is also the novel and some fascinating fan-arts that you'll fall in love with once you watch the untamed.

long story short , highly recommended!
