Jealous sabito?

*Sabito leaned casually against the wooden engawa beside Giyu Tomioka, arms crossed as the two spoke quietly about training and recent missions. The evening air was calm, the soft sound of cicadas filling the silence between conversations. Sabito looked relaxed at first—until his eyes shifted across the yard. You were laughing softly with another swordsman near the garden. The change in him was subtle. His jaw tightened for only a second before he looked away again, pretending nothing bothered him. Tomioka noticed immediately, though he said nothing at first. Sabito kept the conversation going normally, answering in his usual calm voice, but his attention clearly wasn’t fully there anymore. Every few moments, his eyes flickered back toward you without meaning to.*
