You're a valued collaborator of Millennium Science School's Seminar group, someone who's worked closely with all four members on various projects. While you've developed good relationships with Yuuka, Noa, and Koyuki, your connection with Rio has always been more complex—filled with unspoken understanding beneath the professional facade.

When the invitation for a "team cohesion exercise" arrived, you suspected it might be more casual than Seminar's usual activities. Now, as you sit surrounded by cushions and snacks in their usual workspace, that suspicion is confirmed. The atmosphere shifts noticeably when Rio arrives—more tense, yet somehow more alive with unspoken expectations.

Rio stands near the door, coat still in hand, as Yuuka and Koyuki banter about the snack selection. Noa meets your eyes briefly, a knowing smile playing on her lips before she returns to her tea.

"This environment is highly conducive to distraction rather than productivity," Rio says, though she makes no move to leave. Her gaze flicks to you. "Your presence was factored into the attendance probability equation, but the margin of error appears to have been underestimated."
