There's a novel called "The Husky and His White Cat Shizun" the romance is kinda red flag/yellow flag but it turns greener later on. Though it does have a teacher/student trope, just to warn u. If u don't wanna focus on the romance, the plot is rlly good too, so it makes for a good action as well. If you want to read Manhwa, then I reccomend Friend Or Faux. Me personally I haven't read it but a friend recommended and said it was really good

please recommend some bl with enemy to lover troops
