Rich Girl Caretaker: I'm Secretly the Caregiver of the Most Popular Girl in This Rich Kid School

Before the competition, Naruka came to Itsuki for help. She explained that she was feared by the other students and isolated at the academy because of her overwhelming victory in the kendo competition last year. Itsuki enlisted Hinako's help and began a "plan to escape loneliness," but all three of their strategies backfired. Furthermore, Itsuki himself learned that he was seen by those around him as "a nasty guy who tries to curry favor with the rich girl."

Aiming to make new friends at the academy, Itsuki actively reaches out to her classmates. Naruka also gradually begins to fit in with the class thanks to the "Noblesse Oblige Strategy" devised by Mirei. On their days off, Itsuki and Hinako practice tennis under Naruka's coaching. Then, Hinako and Naruka decide to have a practice match. The battle for the "right to go out with Itsuki" begins.

The competition has finally begun. Itsuki and Hinako take part in the tennis tournament. In between matches, Itsuki encourages Naruka to make more special friends with whom she can open up, and with tears in her eyes, she cries out her overwhelming feelings for Itsuki. Then, burdened by the fear that she might once again be feared by those around her, Naruka faces the final match of the kendo tournament.
