Ren was born wearing a human face..
Inside him lived a monster..ancient, silent, and endlessly hungry. It breathed with him, waited with him, watched the world through his eyes. Ren learned to survive by restraint. No attachments. No emotions. Feelings gave the monster strength
So he lived carefully, unnoticed, hiding the truth even from himself.
Then Yuna appeared.
She spoke to him as if darkness didn't cling to his shadow. She smiled like the world hadn't taught her cruelty yet. The monster stirred at once, recognizing something rare.
Innocence.
Ren understood immediately..she was dangerous to him..
