whynot's Things

Hi! I cannot for the life of me remember this one title to something I was reading before the mass erasure of lists. It’s an omegaverse Manhwa. I remember it was pretty dark. In the later half of the story towards the end the Uke finds out he’s pregnant and runs away. But he finds out he can’t survive without the semes pheromones. So he returned back to the mansion but hides in this surveillance room the seme had secretly been using to spy on the uke unbeknownst to him. It’s then a rlly sad sequence of events where the uke is in this dark room progressively getting weaker from lack of pheromones until the seme finds him. It’s a weird one from what I do remember but I don’t think I finished it and don’t know what it’s called.(╯°Д °)╯╧╧
