Rumi Matsuoka is 50 years old and lives in Aichi Prefecture. She is a full-time housewife who has been married for 25 years. With her two sons now independent and her first grandchild, she is living the second chapter of her life as a happy and peaceful grandparent. She seems to be truly happy, but because she is in this second chapter of her life, she sometimes thinks about her ongoing relationship with her husband. "It's not that I'm frustrated or lecherous, but I would like my life with my husband to be a little more sexy... When we are together, I want him to see me as a woman like he used to, not as grandma." She applied with this desire in mind, wanting to revive the sexuality that she herself had forgotten.
