I think the reason that Tomarry isn’t as popular as some other similar ships in the fandom is because it is impossible to have them as a side pairing.
You can’t just introduce a story and then randomly bring up: “Oh yeah, Harry Potter and Voldemort are a couple.” Everyone would be like: “SAY WHAT NOW?!?”
One cannot simply address these lunatics as a side-note. They are such a crazy pairing they need the full spotlight and a 50k+ word slow burn enemies to lovers arc to make any sense.
