NACR-570 Suddenly caught in a heavy downpour... I can't go home now, my crush, Yozaki Misaku

Mr. Mio, a longing woman who lives in the house next to me. She used to cook for her when my parents were traveling.

Her wet hair, underwear that can be seen through the white blouse... I happen to be without my parents today... I couldn't control my emotions, and Mio-san was drying her hair...
