The threatening letter was not written by Michiru (Naoi Furuta).After Hamura (Kentaro Tamura) was killed, someone had been secretly watching Rui (Momoko Tanabe) and others, and even followed them all the way up the mountain.That person may be Kawato (Shirota Yu) whose whereabouts are unknown, but Rui and the others know nothing about it...

The three informed Doi (Naomi Trouden) of Quan Shui's (Linya Ari) pregnancy and received her help.Even though Izumi is temporarily recuperating, the commercials she starred in are still being played; Rui and Eima (Yokota Mayu) continue their idol activities as a two-person lineup.

Finally, Anping from the spring gave birth to a child.In the delivery room, which was overflowing with emotion, a bouquet of flowers for Quan Shui was quietly delivered.However, it turned out to be the same bouquet of flowers that had been neatly placed at the place where Haura was buried.Everyone speculated that this was the handiwork of the person who sent the threatening letter, and Rui suddenly felt a strong uneasiness that "we may be being watched“"...

At the same time, the police are continuing to investigate the serial murder case in which Michiru became the latest victim.Mochizuki (Soda Ryosuke), who came to visit Rui and others, informed them that Michiru had been killed and asked them if their lives had been threatened recently.

At the same time, Kato's wife Reiko (Kato Rosa) was asked by her daughter Misuzu: When can I see my grandma?” Reiko was speechless for a moment, but Mei Ling continued innocently: “Mom, you said it - we will see her soon.”
