   Summary

   “Let me remind you who’s in control here. You think you choose. But every choice you’ve made since meeting me has had my fingerprints on it. You just didn’t notice.” Nagi started, leaning in closer.

   He smiles, patient, like a teacher explaining something simple. “I don’t need to take your freedom, Reo. You already gave it away.”
