In the opening scene, a man in a pale blueish high school uniform is shown walking through gloomy woods. He abruptly falls to his knees, before screaming as though in pain. In his bloodied hand, he clutches a skeletal, woven doll. The episode formally begins with the Numata family gathered in their living room for an interview by a prospective home tutor. According to the strange man, who had tricked the older brother of the family into skipping his after-school supplemental classes to attend the meeting, the interview was necessary for him to assess whether his potential student truly needed his help. After a remarkable first conversation, in which the home tutor slaps his new student in front of the entire family, he introduces himself as Yoshimoto Koya. In his words, he would henceforth be in charge of Numata Shigeyuki - the younger, problematic son of an otherwise ideal family. So far, Yoshimoto is the 6th tutor to have attempted teaching Shigeyuki.

The episode begins with the home tutor, Yoshimoto Koya, going through his morning exercises while the Numata family eats breakfast. Father comments on how Yoshimoto has completely crossed the civil boundaries of being a home tutor - given he is always in their house very early in the morning - and although mother reports that Yoshimoto does not treat their son gently, he says they cannot break the tutorial contract because then they would have to pay a fine. While his older son Shinichi posits that the tutor may have cornered Father to sign the tutorial contract without reading the fine print, Yoshimoto finishes his exercises and Shigeyuki descends from his room. They both join breakfast. Shigeyuki is not enthusiastic about going to school, but he forces himself to in order to rid himself of Yoshimoto, with whom he has a standing agreement that if he attends to school for a full week Yoshimoto will quit. The home tutor, who walks Shigeyuki to school, raises the hurdle of the agreement between them, saying that if Shigeyuki misses school for even one day, he will become Yoshimoto's dog.

Yoshimoto Kouya (Sakurai Sho), drive a car on the mountain road in the middle of night. On the passenger seat, the anxiety of Numata Shinichi (Kamiki Ryunosuke) raised. The tutor who claim as Yoshimoto, was actually a different person from the person that was reflected on the Tokyo University's yearbook. "I will tell you a part of my story....", said Yoshimoto to Shinichi, and they head into a certain hospital.There is a plate with "Yoshimoto Kouya" name on the hospital room they visit. Yoshimoto Kouya's name belong to a patient who supported by a life-support device, and the patient is his brother. He told a hidden fact. Although it's hard for Shinichi to believe on the first time, it's hard to think that it's a lie as well. In the end, he ask, "Then, what is your real name?". Yoshimoto answer "......Yudai**". Then Shinichi tell this story only to Shigeyuki

Numata Shinichi (Kamiki Ryunosuke), who can't wipe his doubt on Yoshimoto Kouya (Sakurai Sho), found a "Association to sue Yoshimoto Kouya" website. Shinichi sent an email stated that he want to talk with the web administrator, and the reply come to him. Shinichi write about the misdeed Yoshimoto had till now and how much Shinichi want to save his family, but the administrator reply, "There is no adults who you can rely on", and then, "You never had such concerns about Shigeyuki (Uragami Seishuu) at all", somehow he can saw through Shinichi's heart. On the other hand, Kazushige (Itao Itsuji), whose relationship Kayoko's (Suzuki Honami) getting worse, asking where did Yoshimoto kept the recording tape of him and Asami Maika (Kutsuna Shiori). Yoshimoto admitted that he picked up the video but somehow it's overlapped with Shigeyuki's video because of the operational error. But, to Kayoko, he said that he overheard Kazushige and Maika's conversation and recorded it by himself. Yoshimoto said that he can't forgive Kazushige's affair, so he record it for Kayoko's sake. Yoshimoto act conveniently in front of the both side... At such times, Shigeyuki receive a love letter from a girl named Mano Sakura at school. Yoshimoto, who discover it, give a furious support to Shigeyuki. Yoshimoto research all about what a girl would love on a date and handed all of the research file to Shigeyuki, write a reply letter, and setting a date plan for him. In any way, Shigeyuki now pledged to a date, and Yoshimoto's next action would be... . In front of Kazushige, Yoshimoto invite Kayoko.. "Madam, would you come for a date with me?"

We open with something new—Koya’s tutor log for Shige. We learn that Shige’s place in the class ranking skyrockets thanks to his girlfriend and wanting to impress her. The two are now attending cram school together. While Koya plans new challenges for Shige, he talks about setting the stage for the complete family breakdown. Koya talks about the distance growing between Kayoko and Kazu thanks to the affair with Asami. He also talks of Kayoko’s newfound interest in internet stocks and how her trust grows in him daily. We then get to see Shinichi breaking down more and more and have his grades keep slipping.

The episode begins with Shigeyuki narrating his life story so far. He speaks of his brother Shinichi being better than him at everything, and how this made him develop an inferiority complex. The aloofness of his parents and his lack of friends at school did not help either, and after a particularly unpleasant incident in which he embarrassed himself in class, Shigeyuki became a shut-in. That is, until the home tutor Yoshimoto Koya arrived and took over Shigeyuki’s after school studies. Noting the tutor’s unconventional teaching methods, which include making Shigeyuki face head-on the ugly truths of his family’s indifference and his lack of close friends, Shigeyuki ends his soliloquy on a thoughtful note, pondering on his teacher’s motives for interfering with his life. Shigeyuki is then shown in the present, in school, as he is being bullied by the usual suspects. His not-so-new friend, Sonoda, who had turned against him previously but is not back on his side, attempts to defend him against the villains, to no avail. Despite being physically beaten, however, Shigeyuki and Sonoda laugh at their injuries, and appear not to be terribly bothered about being picked on. In the Numata residence, Shinichi, Father, and Yoshimoto the Home Tutor are having a serious discussion about the possibility of Yoshimoto’s tutoring services being provided for the older son of the Numatas as well. Shinichi vehemently opposes this, but Father interrupts his protests by bringing up worries of his son not being able to enter Tokyo University. He then cites the remarkably progress Yoshimoto has made possible for Shigeyuki’s grades, apparently seeing it as enough reason for him to become Shinichi’s tutor as well. Behind Father’s back, and without anyone except Shinichi looking properly, Yoshimoto raises pictures of Shinichi’s documented wrongdoings: pictures of him shoplifting, puncturing bike tires, and raising a cutter blade in front of his peers. Under the threat o

We open this episode with Kayoko’s story through her eyes. She was the pampered princess of her father. She obediently met with Kazushige through an omiai and the two married. Her husband was not the best husband and father, but she felt blessed by her two children…until they hit the teen years and stopped really needing her. Thus she started withdrawing from her own family. Then the scandal hits that her husband embezzled money from her father and her father urged her to divorce him and bring the children to live with him. Kayoko refuses as she doesn’t believe Kazu really did that. And that’s why she’s like she is.

The breakdown of Numata family can't be stopped anymore... harsh words from Yoshimoto Kouya (Sakurai Sho) didn't reach any of the family member, and everyone of them become selfish. Kayoko (Suzuki Honami) who made a lot of debt from stock loss has stop thinking. Kazushige (Itao Itsuji) planned to use company's money ilegally to repay the debt. Shinichi break up coldly with his lover Asuka (Kitahara Rie), and continue to date Tachibana Maki (Kutsuna Shiori) with suspicion. And, Shigeyuki (Uragami Seishuu) circumstance reversed, he become reluctant to the new conspiracy bullying group.

Numata family completely destroyed by Yoshimoto Kouya (Sakurai Sho). There was no conversation between the family on the next day, and no one even try to clean up the living room after the incident. Every each of them not able to adjust the hole on their heart after Yoshimoto left. Kayoko (Suzuki Honami) pull out a big suitcase from the storeroom, and left the house without consult anyone. Kazushige (Itao Itsuji) start to look for job employment, but his elite pride become a nuisance and left him undetermined. Shigeyuki (Uragami Seishuu) refuse to attend the school again. A call from his friend, Sono-chan, made he attend school after a long absence, but once again he trapped on the bullying group. Shinichi (Kamiki Ryunosuke) who left school now spent an idle daily life, and his hatred towards Yoshimoto increased.

Shinichi questions Sara why did Tago Yudai become Yoshimoto Koya. Yudai once told her that he does not want to repeat Souta's tragedy and wants help others like Souta to live strong. He learned that he can't stop all evil intentions in the world, but he can bring up people who can fight against evil intentions. That's why he became Yoshimoto. Not only that he prevented Shigeyuki from being the second Souta, but he also wanted to prevent Shinichi from turning into a monster like Yoshimoto. Sara gave him Yudai's notebook which has written notes about the Numata family.
