Sorry for using your thread. I just recently created this account and cant make a thread. I'm also looking for a japanese novel where the female mc is always reincarnated as the hero's childhood friend. Hero always promises mc that he will return and mc waits for the hero. But hero never returned. Female mc knows her other past lives, so after nth reincarnation, she goes to capital and to change her life this time. Not waiting for the hero to return.
