How will Azusa fit in the sub au, considering he is already an open masochist and kinda submissive?

Admin Mawile: As in regular DL, he’s the exception. 」(￣▽￣」) Azusa is Azusa, no matter what Au he gets put in, and I suppose that Sub Au for him is more along the lines of helping him learn how to hande those desires in a more healthy way than shoving what he wants at people.
