Aoi is born and raised in a wealthy family that people are jealous of. A beautiful and kind mother, a gentle and reliable father, and a cheerful and good-natured me. Aoi is spending her days in a suffocating life, unconsciously playing the role given to her. Then, Tsubaki appears in front of Aoi. Through Tsubaki, Aoi finds peace of mind for the first time.
Aoi and Tsubaki are childhood friends. For the pure and reserved Aoi,
the innocent and free-spirited Tsubaki is her idol. It is always Tsubaki who helps Aoi out of her cramped world. Aoi eventually grows up.
