and this the chapter you're referring to https://www.mangago.zone/read-manga/drugless_sex/uu/d_v-1-chapter-6/pg-1/
Thank you!!
It had multiple stories but I can only remember the one, the uke and seme are living together and the uke is more obviously possessive of the seme. But while they're eating the seme reveals that it takes a certain about of years for all your cells to regrow which means the the uke's body is made of things that the seme fed him. Meaning that the uke belongs to the seme. Sorry if this doesn't make sense, my memory isn't always great.
