Matou Kimi, Hokorobu Watashi

Yui Nanjou has a "cute" figure and frame, and all of her attempts to look more mature at 28 have been futile. Everyone at her work place treats her like a small animal, and she's on the verge of giving up until meeting Mizuho, a kimono-clad beauty the same age. Taken away by her, she thinks to herself...

"If I wore kimono like she did... then maybe I'd look more like an adult..."
