JxBxJxBxJ

Joker noticed that he have crazy love.
real Batman never love him, yet he want Batman.

I hope Joker sometimes sleeps with Harley instead of Batman.
（naturally I like Joker×Harley！it`s very very cute！）
I`m sorry for that idea...But the story is fascinating to me.
the two rivals are detesting and needing each other.
If it is the strange love of wanting to dominate a partner,
either J/B or B/J makes no sense.
