   Summary

   Maybe being roommates was a bad idea. Sanemi had never been strict and old-fashioned when it came to things, so he thought having an Omega roommate would be perfectly fine. He thought both would be great at controlling themselves and keeping away when one of them was in their cycle. But for the first time, when he can't go to any friend's houses during his rut, he finds it a terrible idea to have a roommate like Giyuu.
