Let's talk

Alright many want Eris in the harem and I want to ask a very important question.

should I add Eris to my mc

or just let him be with Rudy?

==========

if you agree in adding Eris then answer this one next:

should I let the mc be with Eris and Rudeus

or let him be with Ghislaine when they teleported?

Any suggestion in the scenario comment here to help me map out the story.
