@InVinsybll Double ships are common, or as yaoi fans call them twin-copy pairings. It's basically when someone likes one person, but doesn't want to see them shipped with anyone else. Doujins are popular for expressing this. Also, when a character has a sort of alternate personality or battles with themselves mentally there can be the copy ships. And there are the cases like Ichigo, where him and Kon look alike due to the body swaps, where there can be double. That sort of thing, lol.
