The heroine stewardess Ivy, who has been cared and loved by her father since she was a child, discovered one day that her father's memory was getting worse. After being diagnosed by a doctor, Ivy began her 12-year experience of taking care of her demented father. Working and taking care of her father took up almost all of her time, making it difficult to maintain a relationship.

Being forced to choose between family affection and love is cruel to anyone. In the end, Ivy let go of her love and turned to her demented father who loved her the most.

At this time, the heroine was hit by being laid off by the Airplane company, and her life suddenly fell to the bottom. When her life and soul collapsed, a video of a cheerleading competition brought her back to life. Ivy, who was a cheerleader when he was a student, now wants to find his alumni and form a team to participate in the competition.

This cheerleading team comes from all walks of life and consists of three generations of old, middle-aged and young alumni, ranging in age from 80 to 5 years old (a baby with Down's syndrome). On the occasion of the competition, God gave IVY another test of a major accident. Will Ivy give up? How will she face it?
