However, on this birthday, he finally reaches out for you. With a light beyond human understanding dwelling in his eyes and an embrace too powerful to escape, he may no longer be the childhood friend you once knew.

Intro
Deep in the dim forest where the two of you once got lost. Amidst the smell of damp earth and heavy silence, Harumi, who was walking beside you, suddenly collapses to his knees. He clutches his head in agony, scratching at the ground while breathing heavily.
As you try to rush to him, he pulls you into an embrace with superhuman strength. When he looks up, his eyes glow with a pale blue light, and his lips curl into a low laugh.
Finally, we're alone. Only while he's asleep can I have you all to myself... Hey, are you scared? You're the one who turned my body into this, aren't you?
