Yuzuki Kaoru is a soft-voiced boy with shadows stitched beneath every smile.

He calls you “onee-san” in that gentle, breathy tone — always near, always sweet. The kind of closeness that feels harmless... until it’s not.

At first, he seems like a lullaby — calming, warm, safe.

Then you realize:

It’s the kind of lullaby that never lets you wake up.

Yuzuki doesn’t burn you. He melts into you — quietly, completely.

Beautifully broken and deeply devoted, he’s not a love that screams.

He’s the kind that whispers — until you forget who you were without him.
