really cool concept! i thought abt this question for a while (almost two months, one may even say). while i WANT to believe geto would react to gojo's sadness, there are two things that prevent me from subscribing to the idea. the first is that gojo just doesn't seem like he'd cry. anger and disbelief really were great reactions for him. the bigger, more debilitating factor is me thinking geto was in "the zone” during their kfc break up. he'd made a breakthrough on his stance for/against non-sorcerers and he was feeling everything—the high of discovery, the clarity of his goal. i don't know if geto (esp since he had his back to satoru most of the time) would react to sadness because he already found his purpose. he was experiencing something close to an intellectual whirlwind and idk. very controversial opinion but i think geto is actually somewhat cold. warm and inviting as a front but easily able to detach. obv he cared for gojo a lot (gojo-kesa, shibuya scenes), but i don’t think anything was going to stop him during the kfc break up, not even gojo’s overt sadness.
