I am so conflicted when it comes to ships... Like, I would like Harry to be with Ginny, Hermione and Luna at the same time, but I don't want Hermione to be with Ron.
But generally I was really disappointed Buffy and Angel didn't become end game, same as Sora and Tai, Ash and Misty (although I don't dislike Serena either).
Other heated ships that come to mind are from The Vampire Diaries, with the whole Stelena/Delena thing going on, or also Klaroline... Though that isn't technically off the table.
OH and while it wasn't shown in the end, Kiyomaro from Gash Bell is also a case where I want him to get with both girls at the same time because I can't decide! Mizuno is sweet but Megumi probably fits him better aaaand idk.
I mean, technically I don't pay too much attention to this kind of stuff, but it can be fun sometimes.
