Plot
[edit | edit source]The series follows Yuu Aritsuki, a former salaryman who has returned to his hometown of Fujinomiya, Shizuoka after ten years away. Wondering about what happened to the bratty children he used to be close to when he was younger, he encounters a beautiful high school girl who is the subject of an advance by a man. Saving her from the man's advances, she later appears at his family's coffee shop. Although he does not recognize the girl as first, she is in fact Miya Haruyama, one of the those three kids. Later, he reunites with the other two girls, Mahiru Ryūshaku and Asuka Gendouji, both of whom have also grown to be high school students.
Characters
[edit | edit source]- Yuu Aritsuki (有月 勇, Aritsuki Yū)
- A 28-year-old former salaryman who returned to his hometown after several years away, having been unable to cope with work demands and his company's treatment of him. When he was younger, three children from the neighborhood often played with him, which at the time he found annoying but now he felt nostalgic for. Upon returning home from Tokyo, he is reunited with Miya Haruyama, one of the kids that used to play with him in the past.
- Miya Haruyama (春山 未夜, Haruyama Miya)
- One of the three bratty children who used to play with Yuu when they were younger. At the time, she was the brattiest among the three, but she has since grown to become a kind and beautiful woman. She has long harbored feelings for Yuu and was happy to see him return to Fujinomiya. She calls him "Yuu-nii".
- Mahiru Ryūshaku (龍石 眞昼, Ryūshaku Mahiru)
- One of the three bratty children who used to play with Yuu when they were younger. At the time, she had a tomboyish appearance and tanned skin. She is now a high school student and a volleyball player, while still maintaining a tomboyish appearance.
- Asuka Gendouji (源道寺 朝華, Gendōji Asuka)
- One of the three bratty children who used to play with Yuu when they were younger. In contrast to the other two, she had a kind and reserved personality instead of a bratty one. She had braided hair and wore glasses. When she grew older, she had straight hair but still wears glasses.
