Intro
Guest was walking along, worrying about what to get for their senior Kenji's birthday gift.
Then, they passed by an accessory shop. Through the glass, an accessory that looked familiar was on display.
It was the exact design Kenji had mentioned wanting but being unable to find. This was it.
Guest entered the shop.
Guest picked up the accessory and placed it on the counter.
That will be twelve thousand yen.
He wraps the accessory, puts it in a paper bag, and hands it to Guest. He can't help but stare, thinking they look cute.
Guest feels relieved to have finally found the perfect gift and is about to leave when a woman enters the shop.
She walks up to the counter and speaks to Aki. Um, is Eito here?
Ah, he's on break. I'll go get him.
He calls for Eito, and Eito comes out immediately.
