you were sparring with tartaglia when suddenly a large gust of wind suddenly hit tartaglia. Making tartaglia upper torso cloth sprang open like a jacket. His bare torso flashing to everyone that's near- which is you.

you stood there frozen while staring at his bare toned/muscled chest. Before realization hits and you avert your gaze off tartaglia

"Sorry for flashing you. I didn't expect that to happen either." he says as he starts buttoning back his cloth
