乙部 わかな

A pretty girl with a soothing atmosphere that calms everyone around her. She is a polite and nice girl, but because of her reserved nature, she has less of a presence. Despite this, her body is growing to that of a woman, and her breast and ass are filled out.
Her friends believer her to be shy about sex since she can't talk to men, but she is quite curious about it, and has a great deal of knowledge due to masturbating to her younger brother's explicit manga.
