After Transmigrating, I Won Over the Heroine

The story begins when a young woman accidentally transmigrates. She then sets out to win over the female lead, gradually falling for her along the way. At the end, the two young women walk side by side toward a new frontier, and from then on, they stay together until their hair turns white.

(The female leads in the different planes are all the same person.)
