Salon Diana

"Girls who love to lie, come to my salon." Arisue Rio lives by a single, unwavering philosophy: outward appearance is everything. She proudly shares this belief with Irima Yoshitsuki, a male nail technician, who responds by adorning her nails with a specially crafted, cursed gemstone. He then makes an extraordinary claim—if she ever kisses a boy she does not genuinely like, time will rewind. Skeptical of such a bizarre assertion, Rio dismisses the warning entirely and goes about her life as usual. However, her disbelief is shattered when a remarkably cute junior student confesses his feelings to her. Caught up in the moment, Rio agrees to date him, and their relationship quickly progresses to a kiss. Instantly, the impossible occurs, and time abruptly rewinds to the day before the confession took place. Thrust into a supernatural loop triggered by her own dishonesty, Rio must now navigate the consequences of the curse placed upon her manicure. What began as a simple visit to a nail salon has transformed into a complicated struggle against time itself, forcing her to confront the true meaning behind the words she so casually ignored.
