Any recs for genius MCs as in intelligence or several steps ahead of everyone? Examples:
-Yuukoku no Moriarty
-Tomodachi Game
-Weak hero
-From the Red fog
-Death Note
-One Outs
-Dareka o Norawazu ni Irarenai Kono Sekai de
-Youjo Senki

And etc? I don’t rlly want smth like Tomb Raider (love that manhwa but not what I’m looking for) but smth a bit more serious and with more depth?

Or give me some rlly good mystery that’ll make me think a lot and when it’s solved, you’re like “ohhhh I see. I never thought about it that way”.

Now that I think about it, I have never cried in a bl manhwa/mang/manhuas even for once but I feel pain ofc but not actually to the point of crying. Can someone recommend me a story that will totally hurt me? Get me depressed for days or what. I don't have any class so I just wanna take the time to get sad or mourn or something.

just wanna share the feeling
