A girl attending a public girls' high school who recently moved to Saitama Prefecture. In her hometown, many kids engage in compensated dating, so she started doing it casually with her friends. She's already had several experiences with older men she met through dating sites. Today, she came riding the Saitama line to hang out in Ikebukuro, but was approached by an older man who invited her to a love hotel. At first, they just had tea and meals while chatting, then enjoyed karaoke together inside the love hotel.
