This scenario is called...

Disappearing Act

It was the beginning of another day for Quartet Night, even though they had been arguing lately they knew they still needed to work together for the SSS. Yet something was different that morning, as everyone went to the kitchen for breakfast a cheerful face wasn't there. They waited a while and he still didn't show up. Yeah, he likes to leave and go on his drives, but... just something felt off.

Finally Ai stands up and says, "I'll go check and see if he's awake... he did say he wasn't feel well yesterday at dinner." It was true that Reiji didn't eat last night as he had an upset stomach, or at least he said that. When Ai went over there he knocks, but he let out a small surprised noise when the door opened a bit on its own. He pushed it open more and saw a neatly made bed and no Reiji. He turned to face the others, "He's not here."

Ranmaru seemed to actually grow worried for once, "Was there something we missed? It's not like him to not tell us where he's going anymore after last time." Camus scoffed, "He needs to hurry and get back here! We only have a month to get this routine off the ground and ready!" Ai seemed to be thinking, "He has been acting strange ever since we started having conflict over the dance steps..." Ranmaru went to the door, grabbing his jacket. "Kurosaki! Where are you going?!" Camus shouted.

Ranmaru looked to them, a serious look on his face, "To find Reiji... something doesn't feel right..."

(And we would start there or at the beginning of the scenario, we can also start before Ai Checks to see if Reiji is there, or I have other starts in kind as well. It starts out as a full Quartet Night RP, but later changes to ReiRan if we decide to go that route. It has a chance to go extremely angsty, but I can dial it down if you would prefer.)
