A Quick Transmigration Story in a Matriarchal World

I'll leave the title like this until I think of a better one. Quick transmigration, no splitting into fragments, transmigrating together. In some worlds the protagonist loses her memories; sometimes both retain their original memories, sometimes the male lead has no memories, sometimes the female lead has none, and sometimes neither of them remembers. Some worlds have a matriarchal setting, while others have a normal, non-matriarchal setting. The female lead will not give birth. There's no guarantee that the bodies the leads transmigrate into in each world will be virgins. The stories are in no particular order and include, but aren't limited to: The Bug in a Reborn Pampering Romance (modern setting; the male lead's original body was a disposable character killed off by someone reborn. He slaps the scum in the face and wins back his wife; both retain their memories.) Infinite Heartbeats (a dating reality show for ordinary people; both have amnesia.) Showing Off Our Love Is Addictive (non-matriarchal setting; a reality show like The Amazing Race; female CEO X male celebrity; the female lead retains her memories.) Peerless (the male lead's original body was a pitiful substitute who was forced to marry in someone else's place; the female lead retains her memories.) My Wife Is "No Good" (a pseudo-insectoid setting inspired by ant colonies, with three sexes: winged female ants, wingless female ants who cannot reproduce, and male ants. A wingless female ant from the bottom of society X a male ant adored by everyone; the male lead retains his memories.) You Are Desire Itself (interstellar school setting; a female lead who has an orgasm just from smelling his pheromones X a male lead who steals clothes and cuddles them every night while dreaming of sex; includes pheromones; both have amnesia.) Guide Training Camp (female Sentinel, male Guide; a Guide 101-style talent show designed to train and support newcomers, with no group debut at the end. Those who rank highly get priority in choosing matched Sentinels; both have amnesia.) Two-Faced (non-matriarchal, modern setting; a female top student who's aloof in public but a refined scoundrel in private X a wolfish delinquent who's a terrible student and gets teased instead of doing the teasing; both have amnesia.) Cultivation, beastfolk, transmigrating into a book... Theme: Across countless worlds, you alone remain the same
