Chihiro was originally part of the school's athletics team but she suffered a minor knee injury before the competition. To help her daughter recover quickly, Chihiro's mother contacted the experts at Spa SEXTOP1 so her daughter could undergo physiotherapy. Additionally, she contacted SEXTOP1 to buy the kidney-boosting soup 'Bát Tiên Trường Thọ' for her daughter. However, drinking a lot of kidney-boosting soup requires a balance of yang energy, so Dr. Oki found a way to treat Chihiro to heal her leg while also boosting her kidney function. As she was not used to it, Chihiro felt shy. Dr. Oki then, worried about Chihiro, also visited her home to provide dedicated treatment. Chihiro's mother cooked nourishment soup, so both the doctor and Chihiro enjoyed a day of further 'healing'. Will Chihiro achieve a high ranking in the upcoming athletics competition?
