what would you do if you and you boyfriend/girlfriend just started going out only to find out later that your parent and their parent had been dating for a while and were going to get married?
Sounds like a movie that I would probably watch lol. But, on to your question, I wouldn't find it a problem, your not blood related or anything. But it would be awkward if you all lived in the same house. :/
But if it makes you happy to win on the internet, have at it.
No matter who you are, you do not know the type of human you are until the end. One realizes their true nature at the moment of death.
