Salon Diana

"Girls who like to lie, come to my salon." Arisue Rio firmly believes in the principle that "the outside is the most important." When she says that to male nail technician Nojima Yoshitsuki, he puts a specially made, cursed gem on her nails and told her: If you kiss a boy you don't like, then time will rewind. Rio didn't believe it but after being confessed to by a suuuper cute kouhai, they started dating and kissed! After they kissed, time rewinded to the day before?!
