I don't know...since bj alex was made by the same author it feels like it'll be like that. Also can we not forget about painter of the night? The top was just as worse as jaekyung yet he changed in an instant after realisation hit and it was the biggest plot twist ever.
Yes I finished reading painter of the night and to be honest his change was understandable in my opinion, it wasn't a sudden change, he slowly started to care for the Uke and treated him well, he even gave in to his father just to protect the Uke from execution and before that he killed those who tried to rape the Uke, he was also willing to leave the Uke with his sisters just to keep him save. Completely different than this.
As for BJ Alex.... well, it was just a clichê ending as I'm sure this one will also be
Safe***
Both tops are crazy in my opinion but I feel like.. the second top will fall hard for the Uke. No redemption for the first top, nope.
