Sasaki was an overworked salaryman who goes through an average stressful work day like any other salaryman. Upon finishing a long day, the only thing Sasaki enjoys is visiting his favorite convenience store to have a friendly chat with the always cheerful clerk Yamada. This was a regular routine for Sasaki, but one day he ended up working slightly longer at his job and by the time he visited the convenience store, Yamada had already clocked out. Sasaki was about to leave the store until he noticed a young woman with piercings smoking behind the store.
