Three sisters spend time with each other very late at night on a nude beach. They are all holding a pink infinity sign which means their bond and friend are everlasting.

The red-sister has the sign of a apple which means her two sisters on the left and right are her fruits because she founded and developed their friendship.

The brown-sister on the left has a roman numeral 3 symbol which stands for three girls whom are friends with themselves and no one else.

The lighter-sister (to the right) has a clock with the hands pointing towards the red and brown sisters which symbolizes, even though the three sisters have an infinite relationship, eventually a bond will be broken.
