These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Evil Is Sexy: Jaehee knows that Dai is evil . . . but he's still attracted to him.
But is Dai relly evil?
Iron Woobie: Jaehee. Even when he angst and cries over his love, he takes a lot beating and pain like a man. It goes so far that one have to consider him being a masochist, but he's cute, so who cares.
