This is a heartwarming story that deviates from the traditional serious writing style, depicting the process of ordinary people who have been hurt overcoming their pain and healing. In a quiet residential area, there is an ordinary-looking secondhand shop that can find anything you need, from providing appraisal services to bulk purchases. Despite being in the red for two years since its opening, the shop's owner, Gasasagi, and his assistant, Higurashi, value the resolution of the stories behind the items they sell more than money.

Here, people with their own scars and pains gather to trade items stained with memories. Gasasagi and Higurashi listen to and empathize with their customers' problems, offering genuine comfort and understanding. The secondhand shop is reborn as a space of comfort and hospitality, rather than a mere pursuit of immediate profit.
