"This was around the time I made my debut. For a while back then, I didn't have anything to smile about at all." The twelve members of VAZZY and ROCK DOWN gather to talk on a special TV program being made in anticipation of December's VAZZROCK Live Flawless concert. Part way through, the topic shifts to Takaaki, Ouka, and Yuma's roles in the upcoming TV drama Shuten. The new show is a spin-off of Sokai, an earlier feature film about the life of Shoin Yoshida. On set, the three are reunited with two of their former costars; talented actors Yusho Toi and Yuzuru Mikaduki. While Ouka grumbles about working with the difficult Toi again, Takaaki keeps smiling and tries to lighten the mood.

"And that's why Takaaki's smile is so powerful... Powerful enough to infect everyone around him." While Takaaki was still a junior idol at Tsukino Productions, an inconsiderate remark from a departing classmate made him doubt his reasons to smile. When Ouka presses Takaaki to open up about it, Ouka remembers the difficulty he also had smiling as a child performer. Ouka wonders, how was Takaaki able to get his smile back? The answer he receives surprises but also reassures him. Meanwhile, shooting for the TV drama Shuten continues as Toi and Takaaki work through their last scene together.

"Of course not. You'll never get the better of your big brother." "Rise & Set," the new show co-starring the Kiduku brothers, has started streaming. With each episode, Futaba receives more praise on social media. Issa starts to feel pressure on set to keep up with Futaba, whose acting skills seem to improve by the day. One evening, Issa receives a text from his old bandmate Takenaka, who invites Issa out for drinks to talk about the show. Later, four members of Tsukino Productions who are all younger brothers—Rui Minaduki, Nozomu Nanase, Naosuke, and Ayumu—join together to form The Ototo Rangers and try to teach Issa to see things from a kid brother's perspective.

Reiji and Ayumu are shortlisted to become the face of a new brand from a cosmetics company. They promptly decide to have test shots made for the final round, but the result unsettles the two deeply.

Ruka and Gaku play the dual lead roles in a play where they stand side by side and could easily be mistaken for rivals. Ruka actually wants to compete with Gaku for who is the best at playing his role, but Gaku doesn't even recognize Ruka as his rival, which sends Ruka into a deep slump.

The time has come: The big festival Vazzrock Live Flawless of the two groups Vazzy and Rockdown is finally starting. They give a short medley of their previous songs.
