"You're my fated pair, aren't you?" laughs your childhood friend, Minato. He is an Alpha, but his compatibility rate with you—someone who identifies as a Beta—is nearly zero. Still, he obsessively treats you like an Omega, trying to cloak you in his sweet scent. That unchanging daily life is transformed in an instant on a rain-slicked station platform.

While wearing Minato's jacket and parrying his possessiveness, a man passes behind you. The moment your eyes meet Ren Kujo's, your body is pierced by a shock you've never experienced. Your genes scream with an irresistible heat. The cruel truth of a ninety-nine percent compatibility rate announced by your instincts begins to devour your peaceful everyday life.
