His son Haruto (Onishi Toshiro) successfully entered a well-known high school. Kaori Saejima (Naho Toda), who should have been immersed in happiness, chose to commit suicide.

While the celebrities in the high-end residential complex “Sky Castle” were talking a lot, Sae Asami (Nao Matsushita) read Haruto's diary stored in the tablet she lent to Kaori and was so shocked that she couldn't speak..What drove Kaori to a dead end was Haruto's hatred for his parents who forced him to study for exams in the diary. Haruto vented this emotion in the diary.

Moreover, the diary also states that Haruto once consulted the examination counselor Kujo Ayaka (Koyuki).A few days ago, in order for her eldest daughter Ruri (Miwa Arai) to be admitted to the high school affiliated with Tokyo Medical University, Saei successfully signed a contract with Kujo and was immersed in a sense of superiority.However, Saying became suspicious of Kujo, who claimed not to interfere in family issues, and angrily terminated the contract.However, this decision was strongly opposed by Ruri!

On the other hand, Nikaidou Kyoko (Higa Aimi), who lost to Saye in the battle for Kujo, also took action this time, determined to get the contract.

At the same time, Izumi Minamizawa (Fumino Kimura), who moved into Saejima's house, is determined to find out the truth about Kaori's suicide and starts writing a novel in order to prevent the same tragedy from happening again.She tried to get information from Saye, Kyoko, and Natsume Misaki (Marijun Takahashi) who were close to Kaori.Saying openly displays hostility and refuses to cooperate.However, the cruel words she said at this time caused “his own fatal situation” in the life of a celebrity...!
