they're trolling, mate

banana fish

Basically almost every omegaverse ever.

Killing stalking? Lmao (≧∀≦)

Let Dai

Lol most people seem interested to troll and respond to trolls.
Banana fish is a nice manga, has a nice ship. But they dont even have canon romance, there are hints, but they dont admit they have romantic feelings. plus its so tragic i quit. I am not a masochist.

Btw you mean general or just BL?
I dunno about general ones anyway.
About BL, here:

These are some manga with such themes. But, for me, my star crossed, destined to be (with none other than the One), one true pairing is Lan Wangji x Wei Wuxian (Mo Dao Zu Shi) (not just MANGA! WARNING: Not a casual read, so dont go ahead and read the manhua in disappointment. Read the other things first)

they asked for soulmates and it clearly says at the end that they were connected to each other soul to soul
