Does anyone know the two black haired man in the veryyyyyyyyyyy last (I think you call it ...

The one on the left is Kim Dokja, and the one on the right is Yoo Jonghyuk. They're from Omniscient's Reader Viewpoint!

I think it is OVR
(=・ω・=)

Do you perhaps know the genres?

I would describe it as action(? like on the lines of Solo Leveling, Trash of the Count, etc). It's not BL, but some people ship them together (they do have their 'moments' lol)! It's one of my favorite novels/manhwas, and I highly recommend reading it bc it has very good plot & interesting characters :D

Thank you!
