This novel is basically a anthology of lifetime's. It's over 5 thousand chapters long, I'm on the 1000th. Each life she meets a guy, who kind of transmigrated with her to that reality though with no memory of formers. She remembers every life, tho back ends it for the station between lives and takes on who each new person was including their ideals/values and wishes. If he becomes an Enemy that life, she Revenges on him too without regret. He always remembers her and their former Lifetime's Worlds just before death. It's ruthless what she does living out these people, playing long 10+year revenge schemes before Transmigration.
