   Summary

   During a joint mission with Obanai, Sanemi finds something—or rather someone—invading his thoughts. Later still, in the midst of their passion, Sanemi find himself yet again thinking of a certain cerulean-eyed, ebony-haired Hashira.

   And then of course, there’s Obanai, who’s well aware of his boyfriend’s oblivious pining, waiting for the perfect time to strike.
