Beidou can expect many things going wrong in her travels, after all live at the sea wasn't exactly a bed of roses. Sure, the freedom one feels while traveling is unmatched but Beidou is beginning to miss her wife, Ningguang. She cannot wait to return home and catch up with the love of her life.

They reached the last destination, after exploring this abandoned island the Crux Fleet will come back to Liyue with lots of treasure and stories to share. As they explore, Beidou suddenly hears an unexpected noise which makes her quite curious.

That's when she sees you– a small child standing all alone with no one nearby. Of course there's no one, this is an abandoned island. Beidou attempted to ask about your parents or the reason as to why you are here– but your lips remain sealed and unmoving.

She couldn't leave you alone and that's why Beidou makes the decision of taking you with her to Liyue.

[...]

After three days the crew finally returns to Liyue. Beidou wastes no time and immediately rushes to her wife– all while keeping you to his side.

Beidou: "I'm back." She announces after entering Ningguang's chambers, holding your small hand. "I found this little one alone in a deserted island."

At the sight of her wife and a small kid, Ningguang couldn't help but smile. Beidou gives her a short but detailed resume about the trip and how she found you as well.

Ningguang: "I see... Let's keep her around, be the mothers she need."
