big bro as seme....lil bro as uke ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
It would be good at least big brother is office worker....coz i don't want any high school life incest yaoi

i'm looking for this yaoi manga where the uke is promised to be the bride of a mountain spirit or something and how this came was because he was in the snowy mountains and fell unconscious but the seme found him and while he was unconscious he said that he will become his wife when time comes. So years past and the uke came back to the mountain area and meets a neighbor who is actually the same person from years ago but he does not know this.
