From Aoyagi to Tenma

Chapter One (Saki): An Impromptu Visit from a Childhood Friend.

Saki had already said goodnight to her parents, and his brother and his "friend" and took the needed medicine to go to sleep, so why was she still awake? She tossed and turned until she succumbed to the boredom and checked her phone. The last thing she wanted to see was on there, the thing she feared the most.
Her friends were texting each other. She usually lets it slide on a normal night, but tonight was not one of those nights, and nobody needed to be awake tonight at this hour. They all had a big show the next day, and everyone in the chat was texting to each other instead of sleeping. Saki could feel the anxiety and stress in each of the messages, all of them sending the same feel to Saki.
They were trying something new for this concert and all of them were very worried it would go wrong. Saki, as the resident bright mood-maker, decided to try to stop the negative thoughts for as long as she was awake.

Honami: i don't know should we call off the concert tomorrow?
Saki: Come on guys!!! We practiced this!!! WE GOT THIS!!!
Shiho: But we putting our full concert, from beginning to end, in the SEKAI. There is a good reason to worry.
Saki: Sure but we've worked so hard on it!!! We can't just give up now!!!
Ichika: if saki is prepared for this then I am too

Saki smile widened as everyone brought in their own feelings and went off their phones got a good's night rest. Saki was about to have a nice, long sleep filled with dreams of her friends, but a loud crash seemed to have shaken the whole house, and Saki was too worried about Tsukasa to just sleep after a noise like that.
After running down the stairs, Saki found herself in the living room, with some figures hidden in the shadows, on nearly illuminated by the moon from the window above. Saki couldn't tell who was who in the room, from the person on the couch to the two beside it.
Saki took all her energy, imagining herself as if Tsukasa found this scene, and asked the question with all her bravery.
"What's going on here, who are you people doing in my house?" The words fell out more sleepily than Saki thought or hoped they would, but the message conveyed perfect for the two people who were standing. They fumbled over each other in the dark and one of them fell trying to turn on the nearby lamp. One of them, the shorter one, managed to hit it and the room finally was properly lighted, and the true scene revealed itself.
The mystery people were Tsukasa and Rui, but the person on the couch was still hidden by a blanket. Saki removed the cover to find Toya, and childhood friend of both her's and Tsukasa, so why is he here this late at night?
"Why is he here?" Saki asked, hoping that either of them had an answer.
"We don't have any clue to why," Rui states, moving closer to the front door, "besides this of course." He picks up a small bag and tosses it to Saki. She catches it and looks inside. Everything in there came from his own room. Music lined the walls as clothes filled the bag, She wants answers, and knows that Tsukasa knows something.
"I'll ask again, to Tsukasa this time. Why is he here?" Tsukasa looks up at Saki, the bags under his eyes become only more apparent as the light hits his tired face.
"Well my and Rui heard the door bell ring so we went to check, and when we opened the door, Toya just fell past the door and passed out. Didn't even make it to the living room. We picked him up and put him on the couch, and you showed up right after that." His voice is aligned but his mind clearly isn't. Tsukasa looked like he was going to pass out any minute now, and that was the last thing Saki wanted.
Saki ran to the closet in her room and brought out three sleeping bags for the three of them. Saki used to have sleepovers with her friends before she got sick, but she still kept the sleeping bags. But by the time she went to the other two, they were passed out on the floor. Saki laid the bags over the other two before getting into hers and sleeping moments after, with hopes and dreams of a successful concert tomorrow.
