Katase and Kohiwa are high school classmates. Liking someone so much it makes your head spin, exchanging kisses with every little chance, touching each other, connecting your bodies... The main story is about two guys in the spring of their youth who find themselves rapidly drowning in one another. Also included in this highly-anticipated debut book are the sweet and heartbreaking one-shots, "Tranquilize" and "The Thorns are Hurting my Cheeks".
