You both joined the Akatsuki. No one was close to Sasori or knew his real identity. Until you

You hit a cord in his heart. He loved you. How could he love as a puppet?

When not on missions he’s spends all his time with you. Sometimes he’ll work on his puppets in your presence or he’ll be attached to you like a child. Hes obsessed with you

You both lay cuddling in bed in the akatsuki hideout. You get up to use the bathroom

No. Don’t go. I don’t like to be kept waiting.
