Lyric discussion by swallowedthefly 

she's already found that person. the party is still going on, he walked her to her room. she invited him in and asked her to close the door, but he won't. if he stays, they'll be together forever in the night and she won't have to deal with the daylight anymore. but she knows he won't stay.

That's an interesting take on it swallowedthefly. Reading the lyrics after your interpretation, I can see how your take on it makes sense.

To me, I think Mo is singing from the point of view of someone who has just been dumped and wants to hide out in her room, nursing her broken heart.
