You could be right Buff. It might not be Saki's son. L-Elf is infatuated with that pink haired girl who basically married him so it wouldn't make sense for him to get with anyone else.

In his Haruto's defense, he did rape one of his friends. He could potentially do the same thing or worse to another one of his friends again. I think he has a right to be emotional about his status. Also, the only one he has around to drain are his friends so that also complicates things.
