She has liked the sister next door since she was a child. From the beginning, she set her as a role model and gradually wanted to stay by her side. It was not until she was in junior high school that she panicked when she saw her sister confessed to her by an outstanding boy next to her...
A new family recently moved next door with a sweet and soft little sister. Perhaps because the family was too career-minded, she slowly found a warm corner in her little sister. However, her mother's force forced her to go abroad and she broke off contact with her sister. However, she has been waiting for the opportunity to regain the time to get along with her sister (Wait for me, you are mine...)
Concept: The warmth of the younger sister makes the cold older sister move towards the sunshine, but it also makes the older sister unable to live without her (five years difference)
