  Worse unfortunately, he’s hot.

  Summary

  Renji explores abandoned buildings for the thrill of it.

  Obanai keeps appearing in them with knives, bruised knuckles, and the exact kind of face that makes bad decisions feel reasonable.

  Neither of them believes in ghosts.

  Unfortunately, Tokyo’s abandoned places are full of far worse things:
  masked men, blood trails, hidden rooms, stalkers, livestream disasters, and whatever the hell keeps following them through condemned buildings at three in the morning.

  Also unfortunately:
  surviving horrifying situations together keeps making them want to kiss each other stupid afterward.

  Summary

  Obanai shows you the scars beneath his bandages expecting pity at best and revulsion at worst.

  What he gets instead is your hands in his hair, your mouth against every inch of ruined skin, and the horrifying realization that you might actually love him exactly like this.

  • not to be dramatic but this changed both of them permanently

  Summary

  Obanai spends years believing the scars across his mouth make him difficult to look at.

  Unfortunately, that becomes someone else’s problem the second you see them.

  Companion/sister fic to “Beautiful is Boring,” except this version is significantly more unwell about it.

  • my fbi agent is probably extremely horrified and a little turned on

  Summary

  Local men discover that unresolved tension does not, in fact, go away when ignored aggressively enough. Guys please there are easier ways to confess than whatever the fuck this is.

  The line between “I want to kill him” and “I want him carnally” is thinner than expected.

  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?
