Tamagawa-san, Did You Appear?

The popular AV actress Miyama Yuri has suddenly announced her retirement. At the same time, Shikishima, a convenience store manager and her biggest fan, finds himself at a loss, unsure of how to move forward without her in the industry. Amidst this, a girl named Tamagawa-san shows up, applying for a job at Shikishima's store. Coincidentally, she bears a striking resemblance to Miyama Yuri. This uncanny similarity leaves Shikishima torn. Should he ask Tamagawa-san if she's ever appeared in AVs? But in today's politically sensitive climate, such a question feels risky... Who is Tamagawa-san really?
