pretty sinilar to what you’ve said
Yesss it is!! Thank youuu I've been looking for it for a while
Looking for BL/Yaoi manga. I only remember the ML is like a devil which being sealed for hundreds years in a cave and MC is ordinary human who released the seal accidentally. Then they went on a journey together. There are also side couples whose MC turn into devil but hide it by dying her hair colour. I forgot the title but I really wanna read it again
