Amicus x Neferu, hot~~~
[Edit: Fine. Amicus x MC x Neferu. There, everyone happy.]
I was thinking more along the lines of Marco/MC x Neferu (and/or possibly Amicus included in that as well) while at the same time maybe mixing in a few other characters into that as well like say for instance Cassius, Alexios, and Cato if he can turn out to not be evil at the end through the main characters actions and interactions toward him through some method used in one way or another.
