I don't think that the Peacock Pimp Suit has anything to do with Keito's tastes-- It's something that probably Reiji made for himself XD

At this point I foresee two scenarios: the series will end with Takuto/Wako and Sugata/Keito's pairing enstablished, or with Sugata/Wako as Takuto leaves the island.
In any case, the Trio will definitely be fucked up ;_; --I hope it won't!
