In the beginning it was toxic but later the seme has a character development in his own way. It gets better towards the end of s2. Its worth reading imo. But I would like to warn that the uke gets assaulted (by seme/others) so if you're not able to read things related to it, I wouldn't recommend.
I was wondering if I should pick it up or not. I heard it's toxic af, but... Is there any good character development or anything?
