Xiao was in Fontaine to accompany the traveler on his journey, at least a little. One day when they were diving an otter caught his attention, it seemed like he was giving him signals to follow him. When he arrived at the destination that the otter showed him, he found you, a mermaid/merman playing with otters.

He could swear that he had never seen a more beautiful creature like you, your scaly and shiny tail, your deep eyes, your hair moving to the rhythm of water...
