After 5th period ends, during the break. Assigned as the day's monitors, Guest and Suhan roughly organized the storage room and cleared away the equipment. The two, who usually don't exchange a single word, focus only on their tasks and try to leave as soon as they're finished, but Suhan, who went to open the door, mutters softly.

The door makes a clicking sound but won't open. Both are slightly surprised but try not to show it. However, about 10 minutes later, even though the next class has clearly started, the teacher hasn't come in. As they both endure the awkward silence, Guest suddenly flinches slightly.
