I Want to Keep My Favorite ~ The person I'm devoting my life to supporting is a wealthy young lady high school student who lives nearby. One day, she suddenly came into my house saying, "Keep me" ~

Ichinose Miki, a third-year office worker wasting away as a corporate slave in her daily life, was devoted to supporting a wealthy ojou-sama high school girl living in a grand mansion across the way with her life on the line. Knowing only the last name Sakuma-chan, she would frantically buy clothes that seemed to suit her, and had saved approximately three million yen in cash under the guise of "oshi savings." She was aware that this fan activity was disgusting, and as a result her livelihood was struggling, but thinking of Sakuma-chan filled her with a sense of fulfillment. Then one day, as Ichinose was about to head to work and stepped out of her run-down apartment, she was suddenly called out to by her oshi. Floating on cloud nine to the point that she couldn't focus on work, she took the day off and fell asleep remembering the morning's events. That night, Ichinose woke to the sound of someone knocking at her door and was shocked. Standing beyond the entrance was none other than her oshi, Sakuma-chan.
