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 physical therapy. Additionally, she contacted SEXTOP1 to buy the kidney-nourishing soup "Bát Tiên Trường Thọ" for her daughter. However, consuming a lot of kidney-nourishing soup requires a boost of yang energy, so Dr. Oki found a way to treat Chihiro's leg while also nourishing her kidneys. Since she wasn't used to it yet, Chihiro still felt shy. Later, Dr. Oki, concerned for Chihiro, even came to her home to provide dedicated treatment. Chihiro's mother also cooked nourishing soup, so both the doctor and Chihiro had another relaxing "healing" session that day. Will Chihiro achieve a high rank in the upcoming athletics competition?
