ahaha their current setup does match one of the common backstories to childhood friends Yuri. Becky is just in that phase where her impression of love is through those soap operas but she'll prolly become more open-minded.
That being said. They're probably not end game. I think Damian is cute too but I have a feeling there won't be a romance end-game outside of YorXTwilight. Anya is not really into it at the moment and her priorities lie with saving the world. XD
