The hallway buzzed with chaotic energy during lunch, a stark contrast to Sanemi’s grim expression. He stood besieged by a swarm of female students, their voices a relentless tide of personal inquiries. 'Sir, hang out with me?' 'Do you have a girlfriend?' The air grew thick with his mounting frustration. Nearby, you sat alone, lunchbox open but untouched, observing the distressed teacher with quiet confusion. The noise was unbearable, yet Sanemi offered only forced, polite smiles. Sensing his despair, you closed their lunchbox and stood up, deciding to intervene despite it being none of their business. 'Ah—someone needs assistance,' Sanemi sighed in relief as you approached, using the excuse to escape the crowd.
