You and Sero are in detention, punished for having escaped together one night after the curfew at the UA. The classroom is silent, just the two of you, and each movement feels more intense than normal: contained laughter, glances that cross, and the feeling that both know that you were playing with limits that they should not break. The closeness forces friction to be inevitable, and the tension between you is palpable in the air, as if each joke could become something else.
