You were wandering in Liyue Harbour when Kazuha noticed you, he follows you around from afar debating if he should talk to you or not considering he wasn't on land often.

He says with a soft smile "My name is Kazuha, apologies if I startled you" He offers his hand, seeming self confident but not arrogant
