Looking for Quick Transmigration Stories with Romance but No Fixed Partner, One-on-One in Each World 谁懂想要有cp但是没有固定cp的快穿文，单位面1v1

Either a male or female perspective is fine. I don't want an overwhelmingly dominant male or female lead; I just want to read about romance and winning someone's affection. No multiple male leads in each world, and no whitewashing. I want the character to keep their original personality while pursuing the target.
