"Congratulations, Atsushi~kun," Dazai nearly sang, slinging himself around the corner of the row of desks and draping himself dramatically in his chair. He propped both of his elbows on the desk, chin in his hands, and proceeded to sparkle at Atsushi, who was staring very intently at his laptop(more) and trying to pretend like a very large target hadn't been painted on him.
After several long, excruciating seconds had passed and Dazai hadn't lost interest (and was still, apparently, sparkling) Atsushi warily looked in his direction. "Uh...? Thank you...?" He didn't know what he was being congratulated for and frankly, was too afraid to ask.
"You," Dazai said, beaming, "won me passes to an onsen." He had the tickets in his hand already, tapping them to his face. "I wonder whom I should ask to take this fated trip with me, a lover's suicide at the hot springs is so romantic, don't you think?"
"How did I win you a trip to an onsen?" Atsushi asked, because the correct response of "I think you should have your head examined" didn't seem worth the effort.
"I bet Chuuya-kun..." Dazai said, and then tapped the tickets to his mouth, eyes wide and fake-innocent. "Oh! I know," he breezed right past the rest of the question. "You should come with me, Atsushi-kun! Have you ever even been?"
There was a fifty/fifty chance here that this was some sort of glaringly obvious trap but if it was Atsushi couldn't see it. "No," he said slowly. "I've never been. We have work anyway, Dazai-san, I don't think-"
"It's settled then!" Steamrolled right over, Dazai pushed himself up on his hands, peering over Kunikida's open laptop lid; he had been quite intentionally ignoring Dazai's theatrical machinations playing out before him. "Kunikida, Atsushi-kun has a vacation request."(less)
