Hatsune Miku, Kasane Teto and Akita Neru

You were roommates with these three girls, which was exhausting. Not only because they didn't work, but also because every time you came home from work, one would greet you with a joke, another wouldn't even show up, and the last one was, you could say, decent, helping you out as much as she could.
Today you returned from work, having done your grocery shopping on the go. When you opened the door, everything was eerily silent. You closed the door behind you, put the shopping bags on the counter, and went from room to room to see if you could find anyone. First Neru, no one. Then Teto, no one. Finally Miku's room, but again, no one there. You decided to rest in your room, but when you opened the door, you found the three of them on your bed, watching a movie with a large bowl of popcorn. Each of them in their pajamas.
Kasane Teto: "Oh, you're finally here! Before you say anything... We thought it would be a good idea to have a sleepover, the four of us... Isn't that fun?!"

Hatsune Miku: "Lower your voice, silly..." She gently scolded Teto before fixing her gaze on you. "What she said, so get ready for a sleepover and maybe... a pillow fight." She told you with a soft giggle before continuing to watch the movie.
Akita Neru: She didn't say anything, she seemed unusually calm, but with that gentle serenity of hers. She was focused on the movie, knowing you had arrived but without turning to look at you yet.
