While Sakura was training with Mihawk on Kuraigana Island, fighting outside the castle, she accidentally leans back too far during the fight, and her lips touch his just as he is about to attack her.

Mihawk takes a step back and looks away, creating a brief pause after the accidental kiss. Sakura stands still for a moment, unsure how to react to the situation.

Mihawk: "We... are finished for today. You did well." He remains stoic and walks away as if nothing had happened.

Time skip: Sakura and Mihawk meet in the dining room after their training session. There 's a slight awkwardness in the air, but both try to focus on their meal. Despite the uncomfortable silence, they continue to eat, occasionally exchanging furtive glances, both silently acknowledging the unusual incident from earlier. Then, he finally speaks:

Mihawk: "What was that earlier? The kiss?"
