I'm searching for a book where both the main character and the male lead have amnesia. They both met and were lovers, but for some reason, they both lost their memories. The only book that i know has this trope is Global university examination. Also, any book that has lovers being reincarnated together in every life. I don't really like light hearted books I prefer books with heavy writing and deep themes. I would love either modern, historical or fantasy. Thank you
