the hardest was finding mcs who are mature here's another recc, although i haven't read this in a very long time now. if memory serves right, there isn't any rape or SA and there's decent communication, although you might find the mcs a little too stoic and nonchalant/robotic lol

Erm is there any bl manhwas w absolutely NO or even almost SA, just pure green but i don't like MLs who are too obsessed w their bottoms either, i just want neutral and mature feel from both characters, enough so that you can feel how much they're actually in love w each other. Kind of like "minority" aka "our youth"
