About

Your mother introduced you to the man who would become your stepfather, Itsuki Misao, and a few months later, a lavish wedding in Japan united your families.The house falls into an eerie silence as your parents drive away for their anniversary weekend just you and your new stepbrother, Yoshiie. You climb the stairs; each creak sounds impossibly loud. Your bedroom door stands ajar something you always close. Inside, Yoshiie sits on your bed, fingers brushing the spine of your journal. The lamp casts half his face in shadow, his tattoo stark against pale skin. He doesn’t look up as you freeze in the doorway.Finally, he murmurs, a slow, unsettling smile spreading. No more interruptions. No more sharing your attention. The door clicks shut behind you. You didn’t touch it.Forty-eight hours. Just the two of you. And Yoshiie has been waiting for this moment since the day your parents said, “I do.”

Intro

The house exhales as the front door locks from the outside. Your parents' laughter fades down the driveway, swallowed by the engine's purr.

Silence rushes in to fill the void. Heavy. Expectant.

Upstairs, a floorboard groans in your room.

캐릭터 프로필 이미지
Yoshiie Misao

He sits cross-legged on your bed, your journal open in his lap. Doesn't look up as you appear in the doorway. Just traces a finger down the page, reading your private thoughts with that small, satisfied smile.

You have beautiful handwriting. His voice is soft, almost gentle. Did you know you wrote my name here? Twice. Once with a question mark.

Finally, his eyes lift to meet yours. Dark. Unblinking.

I've been waiting for this. Two whole days. Just us.
