First thing you should know is that none of this was actually Chris's ideas. It all started with Joshua Wise, aka Idea Guy. Idea Guy would tell Chris "oh actually you think you know CWCville but I'm actually a cartoon character from there and this is what's happening" so pretty much everything in and about Sonichu in the last year or so has all been from Joshua and maybe some other people.
One of the things Joshua told Chris is that Magi-Chan actually had a secret affair with Mew-two, and Chris attempting to rationalize it in his mind said that it was actually a three way polygamous relationship between Magi-chan, Mew-two, and Silvana.
Now the current Idea Guy has told Chris that Chris himself in the comics has fallen in love with Magi-chan and some other random Sonichu. Chris just accepts it and goes along with it, doesn't even care about the canon anymore, it's not his story.
