Mu Ying is a good-for-nothing college student who can't do anything for herself and knows nothing about food crops. Her greatest pleasure is lying on her bed in the air conditioning, clutching a bag of chips and watching sports anime.
Volleyball, tennis, basketball, soccer...
Watching the boys in the anime sweat it out always gives Mu Ying a strange sense of satisfaction.
After staying up too late, everything goes black. When Mu Ying wakes up, she discovers she's returned to her high school days as Morikawa Hotaru and has been forced to bind herself to a "Watch Sports Matches" System.
She has to rack up enough audience points to return to her original world.
From then on, Morikawa Hotaru becomes a regular member of the cheering squad in the stands.
On the volleyball court, the little sun still attending Yukigaoka Junior High is moved to tears. "Hotaru supports us at every match. I have to practice hard."
Inside the basketball gym, a blue-haired boy calmly approaches Morikawa Hotaru and thanks her for never overlooking the "Sixth Man."
At the tennis court, Morikawa Hotaru, holding a pot lid and dressed head to toe in protective gear, survives one deadly tennis match after another.
With iris-colored hair and a gorgeous, haughty air, Keigo Atobe presents her with a huge bouquet of roses. "This is my reward for your courage."
Later, Morikawa Hotaru stares at the four invitations in her hands, close to tears.
Nobody told her the national championships for basketball, volleyball, soccer, and tennis were all on the same day!
