Hikaru, a girl who skipped school for the first time in her life, probably because she can't get used to her new life.Although she tried to skip it, she changed from her school uniform to her plain clothes in the restroom in the park, probably because she was afraid that she would be guided around the city from daytime on weekdays.She is questioned by a suspicious man who has been watching from the shadows, and the girl who is still ignorant of the world is taken to the hotel as the man says...She then gets her body dirty with her first ever grown-up desires.Hikaru was covered with cucumber juice, love juice, and juice, and while she was stunned, her obscene heart began to sprout without her knowing.
