Heyy, I think the manga you're talking about is "the man in the mirror" by yukibayashi.
Can someone recommend good smutty bl novels to me?? Not ones that are subtle like the novel "I Just Crave for Your Pheromones" but like "fanservice paradox" "lovely allergin" and "I call my father my elder brother". It's a plus if the smut is sadistic . Please recommend alottt️️️
