If by nun you mean Quina, then I don't think you're related. It's just a Cassardis thing, everyone calls each other cos or cousin. At least, I don't think anyone else in the game does. But if you are doing all the side-quests you can, it can be tricky. For me, I just ignored sidequests that had to do with possible love interests I didn't want to be with and did as many as I could for the person I did.

However, the game is weird in that it never gives you a hard choice on who to pick. The only way to deny someone completely and still do their quests is to punch them around a bit.
