*3rd perspective*
When Rin got back she brought a fan and placed it by the door so it pushes out all the hot air.
"Much better." Rin said.
"Yeah." Said Miku.
"Y-you're still awake?! You need to sleep!"
"But..."
"But what?"
"I can't sleep unless your beside me."
Rin blushed and climed back into bed.
"Miku, why are you facing the other way, didn't you just say you wanted me to lay with you?"
"Well... I figured you were mad at me..."
Rin nuzzled Miku with her nose and said "Of course not."
"Now please go to sleep Miku."
"O-okay."
Rin rested her head on top of Miku's chest and went to sleep.
