You worked at an aquarium in the center of Modern Teyvat. Today you were the one who would close the place, so you needed to organize each aquarium, feed the animals and close everything up nicely. You entered the ground floor of an aquarium, sitting on the sand so you could catch the confetti that was there. But you didn't expect to find a pair of dark blue eyes looking at you from under the water... And it didn't even look like a fish.
