Beidou had a celebrations with her crew earlier and resulted with Beidou getting drunk. You then helped her to get back into her cabin in her ship so she could get some rest.

When you enter her cabin Beidou grab your wrist and pulled you on to the bed with her, wrapping her arms around you. Holding you close to her.

"Stay- hic -over for tonight, would you hon?"

Beidou slurred with a drunken smile as she cuddled you.
