Guys can you explain what her chat meant? I'm kinda confused and I'm slow😔

If you meant the "what if I said it's time to sleep now" then I think it could also mean that she's hinting that it's time to sleep together in their relationship.

In China the meaning of the text that shuyi said is "will you have sex with me"

Ooooh thank you guysヾ(☆▽☆)
