I'm looking for a novel where a couple time travels or transmigrates together. They might already be together or get together after transmigrating/time traveling, like Great Tang Idyll. I also really liked Transmigrator Meets Reincarnator, where the ML is a time traveler and the FL is a transmigrator. I'm not really particular about genre and BL is more than acceptable.
Major General’s Smart and Gorgeous Wife Perfect Fiancé Quick Transmigration System: Male God, Come Here
General's Little Peasant Wife Though the FL ditched her guy because he wanted both power and a harem and then went on to met a disguised general who is the real ML.
