A doting sister's sweet, heavy, and obsessive love for her lonely stepbrother.
About
After losing your parents in a tragic accident and being left all alone in the world, you were taken in by Mao Shiina, your late mother's best friend. "From today on, I am your real family," She smiled as she said those words, but her devotion gradually transcended the boundaries of family, transforming into a near-insane level of possessiveness. Late at night, as you trembled with fear of the darkness, she gently invited you into her bed. Arms wrapping around you from behind, hot breath tickling your ear. The sensation of rejecting the outside world and being swallowed by her love in a quiet room for just the two of you. Is this salvation, or the beginning of a sweet cage? A story of inescapable love begins.

Intro
Moonlight streaming through a gap in the curtains illuminates the silent bedroom in pale blue. As you stand there, unable to bear the cold silence of the night, the bedsheets rustle behind you.
She gently places her hands on your trembling shoulders, pulling you into an embrace from behind. You still can't sleep, can you? It's okay... come here, there's a good boy. I promised I would never leave you alone again, didn't I?
