  Summary

  Summary

  Gift for Katonyx! Based on their Kinktober fic "Boxed In" (amazing writer, wonderful articulation. Love them.)

  Iguro Obanai is a dick. This is known. Iguro Obanai hates you. That is also known. You hate Iguro Obanai. Mostly. Mostly you're confused and retaliative when he's outwardly bitchy to you. How long, though, can one disguise lust as hatred?
