The ending was left so open for a second season that it honestly ruined it for me. I really wanted it to turn from a hate to love story with harmless pranks that developed into natural feelings of attraction but the resulting relationship just seemed toxic. Also, Hai was constantly trying to grope Yin and it wasn't portrayed as playful but forceful. I get that both are teenagers and will be horny, but it was borderline harrassment. I was also hoping for more character development from both guys that just didn't seem to happen.
