This is a story about two girls growing up together.
No matter what kind of ups and downs they go through, the two always get through it together.
There are people who join them and friends who leave them. Nothing fancy happened, everything was ordinary.
After going through many years, the two still trust each other, and they are on each other's side.
One person is extroverted and the other is introverted, a perfect match!
Concept: Life has sweetness and bitterness, and the degree of integration must be just right.
