A fish for a fish

Childe had a favourite fishing spot in every nation he visited. He liked to wind down after a hard day's work and practice his hobby to rest his body and train his endurance. Childe had travelled to Mondstadt a couple of times before, mainly for diplomatic reasons, and despite the nation having vast green plains, he preferred Dragonspine.He had been regularly fishing in the cold mountains, until suddenly, all fish disappeared. This went on for a week, until Childe caught on to the silent competition between him and a certain Traveller to catch the fish.
