"Good and Bad": The origin of "Do-no-ko" is revealed. Viewers are "tired" by the heartless words of "Takagi" Mamiya Shotaro and others.

The ninth episode of the drama series "Good Things and Bad Things" (NTV, Saturdays at 9 PM), starring actors Mamiya Shotaro and Araki Yuko, aired on December 13th. The episode revealed the origin of the nickname "Do-ko" (Do-no-ko), given to Seto Shion, whom Takagi Masaru (Mamiya) and others bullied in elementary school, sparking a stir on social media.

◇The following contains spoilers.

Episode 9 is about a serial murder case that begins with the digging up of a time capsule for the first time in 22 years, and the remaining targets are Takagi and Koyama (Shintaro Morimoto).

Meanwhile, Mori (Furudate Yutaro) is watching a DVD of his elementary school days with Takagi and others at the snack bar "Imakuni," and he reveals that the forgotten "Do-ko," Seto Shion, was once a classmate in Class 1, Year 5, but that shortly after the class reshuffle, he was bullied by Takagi and his friends, causing him to stop going to school and then transfer schools.

The episode also revealed why Seto came to be called "Do-ko." In his self-introduction, Seto said he was "good at music," but during a recorder test, he was distracted by Takagi and the others messing around and couldn't concentrate, missing the last "Do." Takagi then laughed at Seto, saying, "Isn't he good at music? Isn't he?" and "He can't play the Do note, so he's 'Do-ko'!" Seto was bullied, with "Do-ko" scribbled on his notebook and told, "If you touch Do-ko's recorder, you won't be able to do the things you're good at!"

When the reason why Takagi and the others named him "Do-ko" was revealed on social media, comments such as "This is just too cruel...", "The bullying is so bad it's hard to watch", "Those guys were such assholes in elementary school...", "They're the worst", and "I'd hate to be in the same class as King and the others..." appeared, attracting a lot of attention.
