From what I remember it was a female protagonist she broke up with her boyfriend because he was destined to be a hero and have a harem she didn't want to be part of the harem and knew who were the girls and confronted him that he met. (From transmigration..memories??) Something about the villain that she comes across on a blindate?? So far that's what I remember. Uncertain if there is a manga as well.. Apperciate the help!
