@pikapingouin His* and yeah this chapter even mentioned it. However there is a lot of layers to the word cousin. The family clan system is complex compared to the broken nuclear family system America has. In some of these Chinese stories they refer to first cousins as actual brothers/sisters don't know if that applies to everything.
So she's probably like a very distant cousin if not just 2nd cousin. Which is really no big deal. 1st cousins are a bit.... yeah no.
