Summary
The Ōgai and Ozaki households were supposed to be a unified front—a sterile, strategic arrangement signed by “lonely adults.” But under the suffocating quiet of the estate, the boundaries between stepbrothers are razor-thin and volatile. When Dazai slips into Chuuya’s room after a skipped family dinner, a rough confrontation quickly spirals into a desperate, chaotic collision. They both thrive in the wreckage of the taboo, turning the very legal trap they hate into a weapon to unravel each other. But when the door handle turns and Mori steps into the light, the thrill of the game takes on a dangerous new gravity.

Summary
Hatred was easy, it was reasonable even. After everything Dio had done, it was what he deserved. Yet whenever Jonathan tried to reduce his feelings to hatred alone, something stubborn lingered beneath the surface, whether it be his father’s lessons or his own conviction, he didn’t know.
Despite everything, he found himself watching Dio when he wasn’t paying attention. Studying the sharp lines of his face as he read in the library, or the confidence in which he carried himself through the halls. Jonathan hated how effortlessly Dio commanded attention.

Most of all, he hated himself.
