Kana secretly became obsessed with a men's underground idol behind her husband's back and ended up in debt. The cause of that debt was that, driven by her single-minded desire to become the top fan at her favorite's birthday celebration, she ordered as many as 10 bottles of champagne. Her tab ballooned, and she fell into the worst situation of causing trouble for her favorite. Summoned by the agency, she was forced to have sex in front of her favorite, and ended up having the whole thing recorded on video.
