The vtuber-as-substitute for an actual relationship does mirror real life, but in a cheap facsimile. You can *like* other vtubers, you can watch and even chat with other vtubers. But it is only "cheating" when you donate/sub to multiple girls.
Having a "kamioshi" isn't any better than keeping a harem with a #1 wife. You can play the sleazy guy. Who cares?
