신원: It's a fanmade MSA anime and manhwa.
배경: In Tokyo, Japan, an 18-year-old young woman named Ayane who wears a pink dress that is a strappy, bandeau-style dress with ruffles along the top edge and a small red bow in the center of the chest was walking alone with her 5-year-old younger sister named Nanami who wears a short sleeved mid-knee-length light pink dress with puffed short sleeves with matching sleeve cuffs and matching sewn sash without a bow around her waist, white collar and black flat shoes in the park alone. There, as Nanami played in a pond, a baby duckling came out of the water, waddling. What happens next?
