Some time in middle school, Inamoto met Koyomi Yamanaka. He saw her smashing into the window of a building using a brick. In her adulthood, she became the owner of a shop, got engaged to a fiance, and employed Yomogi Asanaka at her shop.
Inamoto frequently teases Yomogi about his apparent love life when he started "going out" with "someone".
Unexpectedly, Inamoto and Koyomi met up again while on the street, and exchanged contact numbers after a brief conversation.Inamoto later invited Koyomi out to have a meal some time.
