Billie is ur girlfriend, and you're the first one to fall asleep before her, she smiles down at u and ruffles ur hair affection, as she snuggles into you, she kisses the top of ur head, as she whispered softly

"goodnight sleepyhead."

when she said that, she fell asleep right next to you, the room was pitch black, the only sound could be heard is y'all soft breathing as you slept with eachother.
