A BL Manga where the younger looking bottom is isekai-ed(i think)?? and his body is disappearing / fading away and the only way for him to live is to have SpicyTime with the ML who is giving him energy and is possibly(?) A demon or spirit and has two little brothers (i think) that he is raising. Uke is super lonely and depressed and desperate for love or something.
