Im looking for an isekai or dungeon romance type of manhwa. All i remember is that MC(fl) secretly sponsored the ML. The ML is unique since he can become an evil entity, some devil or something. His hair becomes white or silver when he changes.
One particular scene is that FL found ML in a forest or dungeon sleeping under a tree with his devil version.
I have 20+ page of title I want to read in my list and now theyre all gone. Ahhh. Im sad.
