Fuiuchi Pink: Saturday (2020)

Blurb:
“If you want to achieve happiness … then you should wear something pink.” Luna Chikai, a bubbly businesswoman, has taken this statement to heart in her everyday life. She loves the color pink and incorporates it in her everyday life. When she visits her client, Dr. Yuhi Hatanaka, she can’t help but notice the lack of pink in the doctor’s office. But she notices other things, like cute tea cups and floral accessories … just no pink to be found. It was at that moment, Chikai made it her mission to bring something pink into Dr. Hatanaka’s office. Perhaps, if there was pink in her office, then Chikai can bring some sort of happiness into Dr. Hatanaka’s life.
