Helppp me find this bl

It's a yaoi I think the setting is like apocalypse or sumn it's a manhwa but it's not colored it's black and white, so I don't really remember that much about the plot but Seme is kind of a soldier then the uke escaped some place then after wandering in the forest he met Seme, it's kind of enemies to lovers trope but not really embodies that I dunno how to describe it anymore please if anyone knows, thanks in advance
