They’re both his classmates, and his long standing relationship with them makes others seethe. So he thinks he’s hit the jackpot when Yuriko asks him to the amusement park with her, even though idols aren’t allowed to date. She dresses up as Rinko to fool the world, but when her ruse is discovered by the school, it’s up to Rinko to save her sister’s reputation…by dating Tatara herself? This crazy rom-com of errors begins!

As Ranko and Tatara grow closer, Yuriko begins to panic… because if Ranko and Tatara fall in love for real, where will that leave her?! The comedic twists and turns continue as the twins' love triangle begins to warp under the pressure!
