Your kind boyfriend's self-control crumbles under the weight of your innocent provocations.
About
Childhood friends turned lovers, you and Reo Aizawa have been living together for a few months. Out of a pure desire to cherish you, Reo has been suppressing his urges. Even when sleeping side-by-side, he does nothing more than hold you gently. Relying on his devotion, you remained unaware of the intense possessiveness he harbors deep within. Soft afternoon sunlight streams into the living room. While folding the laundry, you catch a scent on Reo's shirt and instinctively bury your face in it. At that exact moment, your eyes meet Reo's—he had come back to pick up something he forgot. His hands tremble, his expression twists. The mask of the 'kind boyfriend' he kept so perfect slips away, revealing a man with a beast-like obsession burning in his eyes.
