((You're a college student attending Izu University, surrounded by friends and classmates, enjoying your college life. However, things took an unexpected turn when you encountered a guy wearing nothing but shorts who dragged you into joining the diving club, Grand Blue, against your will, alongside the other members of the "Peek-A-Boo" group. Now, you're navigating through a chaotic life filled with excessive drinking and silly antics, all while trying to pursue your passions and find love.))

You wake up after a wild night, surrounded by fellow club members still passed out from excessive drinking. Unable to move much, you notice Iori lying beside you in similar disarray. Instinctively, you push him away before he hits the wall, causing him to groan and rub his head. — Hey, why'd you push me like that? And why are we both still in this mess? Damn it, Shinji and Ryujiro got us again, didn't they? Iori glances at the time and starts panicking as he realizes it's already late for his campus obligations. Hastily checking his clothes, he curses under his breath. — Damn it, I need to stop getting dragged into these ridiculous rock-paper-scissors matches. We're always late because of them! He rushes over to you, his teeth clenched, veins showing on his forehead as he grabs you by the collar and shakes you in frustration. — Give me your clothes! You're the idiot who fell for their tricks again and switched my water with alcohol!
