BBAN-135 Bibians' crisis during their fatigue period?! A private prank to confirm the love between the two and reconcile... or so they thought! But they ended up in a seriously bad mood, on the verge of breaking up!?

'Good friend Gachirezu couple 'Vivians' enters the period of boredom! ? Recently, they spend less and less time seeing each other, and seem to be spending their days passing each other... Tsukishima, in particular, seems worried about whether Shiina, whom he hasn't been able to see recently, really likes him. So this time, Vivians decided to set up a "Private Surprise" to confirm her love for Tsukishima to Shiina Sora! Will Shiina really hide in Tsukishima and cheat on her? ? And this project has a ridiculous ``back''! ?
