Hikari Takabayashi is a hardworking call center agent for a home appliance company who apologizes continuously to customers, even to rude callers who call just to verbally insult her. She does, however, hide a secret. A love affair with her married boss. One day she was asked by one of her junior colleagues Mika, to take a call from a middle-aged woman named Kazuyo Miyawaki who calls frequently. Upon returning home exhausted after dealing with the caller, she noticed the nameplate on her neighbor's door, "Kazuyo Miyawaki"...

Shiori Yamauchi finds a letter in her mailbox addressed to a Reiko Miura, who seems to be the previous occupant of her condo unit. She opens the letter out of curiosity. In it were the words, "I want to see you. I love you." A few days later, another letter arrived with the words, "I'll come and see you today after a long time." Scared, Shiori did an internet search for "Reiko Miura" and found out that she was the victim of a stalker murder that happened a year and a half ago.
