*3rd perspective*
Rin woke up on the floor with Miku on top of her.
"Miku what are you..."
She stopped when she noticed Miku was asleep.
"Psst, Miku wake up."
Rin kept poking Miku until she woke up.
"...Huh? Rin? What are you doing?"
"I don't know, I just woke up like this."
Miku stood up and reached out her hand to help pull Rin up.
"I uh... I'm going back to sleep. Feel free to join me.
At the time it was about 4 AM.
Rin climbed back into bed with Miku and went to sleep.
A/N finishing the chapter here because I actually need to go to sleep.
