I was looking through HS 60 and this idea came to my mind.
I hope I won't offend anybody here with it, but if so then I apologize.. (such things allowed here?)
I personally think it's just harmless fluff ^^
Sort of summary just in case:
Both Jiro and Hisashi are bored and lonely.
And Hisashi decides to write Jiro an e-mail. And next moment they fly towards each other on the wings of love! ^^
Further stuff is for your imagination to decide ^___^
