A share house with Ryo from the future and three people, 'Yuki Ehana,' 'Shiori Kato,' and 'Hitoko Murakami,' has begun. Meanwhile, the band 'Chahan' by Yuki and his friends is criticized by the critic 'Shuichi Aihara' in a music magazine. The three are called by the president, Yuichi Yanagishita, and if they are criticized by Aihara, they will be dismissed as the end of the industry.
Yuki persuades Yanagishita to withdraw his dismissal if he can look back at Aihara three days later. Meanwhile, Hitoko, who has a crush on her rival band vocal 'Seiichi Izumi', leaves a mark on Seiichi's mixing. There is no function to erase the footprints of mixing in 2006. Ryo, who witnessed it, promised to erase his footprints and instead signed a contract with Hitoko. The content was to have Hitoko, who usually doesn't say her true intentions, say her true intentions.
Hitoko went to a clothing store and her parents' ramen shop with Ryo, and was encouraged by Ryo to say what she really meant. Even in front of Yuki and Shiori, she has a quarrel as a result of her true intentions ....

The office president 'Yuichi Yanagishita' calls 'Yuki Ehana,' 'Shiori Kato,' and 'Hitoko Murakami.' The content was to audition for newcomers at the festival.
The three people who agreed with the prompt answer immediately decided to select a song for the audition first screening together with 'Ryo', but Yuki and Ryo do not give up on the song they chose. The song selected by Ryo is a representative song of the band and is popular, and the song selected by Yuki is a new song with a melody but the lyrics are incomplete. Yuki declares this song a love song and begins writing her lyrics, but she has no decent love experience, so she gets stuck early.
Ryo invites Yuki to take a walk for a change. There, they meet 'Seiichi Izumi,' a rival band vocalist and Yuki's childhood friend. Yuki introduces Ryo as a producer, but Seiichi has a secret feeling for Yuki, so it's not calm in his heart.
Ryo and Yuki then go to see the animated movie 'The Girl Who Leapt Through Time' together. Yuki, who was influenced by the movie, wrote her lyrics and completed the song 'Satellite'. It was decided by the votes of everyone around me which song, 'Satellite' made by Yuki or 'Orange' recommended by Ryo, would be auditioned.
