Despite this, he has a girlfriend and business partner he adores (Mine Kuramae, the local seamstress and Meganekko), and his constant flirting with Shigure turns out to just be a mutual gag they use to bug people (and in Ayame's case, perhaps to discourage the family head from having sex with him).
Ayame Sohma of Fruits Basket is practically the incarnation of this trope: he wears feminine clothes, speaks in a stereotypically 'gay' manner, crawls into bed to cuddle with an unwilling Kyo, and constantly exchanges sexually-charged banter with Shigure that implies more than cousinly affection.
