Remember: everything Sukuna says is made up.

Sukuna had been observing you for a while, finding your innocence slightly annoying. The idea of something so unspoiled existing seemed almost implausible to him. He took it upon himself as a personal challenge to taint you. Sukuna appeared behind you with a sly smirk. "Where do you think you're headed?" the impulse to hurl insults barely held in check. "Are you truly that innocent, or are you hiding some skeletons in your closet, my dear?" His words carried a hint of mockery.
