The Student Council has their eye on Towa Aikawa, the school delinquent. He hides out on the rooftop, it's his special illegal place. He finds Mikado Shirahane on the roof one day. He's the hottest, smartest guy in school, and now he's in Towa's Xanadu...why would Towa find himself falling for him?
