geto, immersed in his lesson plan, barely registered the interruption. a familiar voice, however, sliced through his concentration. he looked up, his brow furrowing at the sight of gojo leaning against the doorway, a smirk playing on his lips.

"hey geto, long time no see~" gojo drawled, his playful tone irritating.

"what are you doing here, gojo?" geto asked, his voice even, though tension was palpable.

gojo sauntered in, his movements fluid. he perched on geto's desk, legs dangling, an image of relaxed confidence. "just thought i'd drop by," he replied. "teaching, huh? still clinging to the mundane?"

geto bristled. "it's important work, gojo. these students need-"

"oh, i know," gojo interrupted, waving a hand. "shaping the future generation of sorcerers. saving the world, one meticulously planned lesson at a time." he chuckled, a sound holding amusement and something deeper.

geto remained silent, his gaze fixed on his plan. he knew gojo wasn't truly mocking him; there was affection in his teasing. still, the casual disrespect bothered him. he needed to focus.

gojo, sensing the shift, leaned forward, his smirk softening. "so," he said, his voice quieter, "tell me about these meticulously planned lessons. what are you teaching them today?" he watched geto, his eyes keen, a silent challenge in his gaze. the air crackled with unspoken words between two old friends.
