At a cozy esthetic salon, a high school sophomore named Hikaru visits for a special summer promotion — a free esthetic treatment. Introduced by a friend, Hikaru is a bit shy at first, but soon relaxes as the session begins. The esthetician, Ishikawa, guides her through a relaxing massage and skincare routine using a special oil designed to rejuvenate her skin and prevent future sun damage. As the treatment progresses, Hikaru gradually becomes more comfortable, even as she's teased about her growing confidence and the possibility of a new boyfriend.
Meanwhile, another customer, Sora, a 10-year-old girl, also arrives for the same special offer. Though initially nervous, Sora enjoys the treatment and is excited about the possibility of meeting her own crush. The esthetician encourages both girls to embrace the experience, promising that the special oil will not only improve their skin but also help them feel more beautiful from the inside out.
As the treatments continue, the atmosphere becomes more playful and intimate. Hikaru and Sora both experience a transformation, not only in their appearance but also in their confidence. The esthetician, with a mix of encouragement and light teasing, helps them through each step of the process, from gentle massages to more intense treatments.
The session ends with both girls feeling refreshed and more beautiful than ever. As they leave, they're excited about the possibility of returning for more treatments and even bringing their friends along. The esthetician, Ishikawa, looks forward to seeing them again, ready to help them shine even brighter.
