Creating Male Yandere Character for a Game, need advice on appropriateness of ethnicity.
Hello, I'm currently making a VN psych-horror dating sim that has a yandere male love interest. He will be the twist villian, kinda like Lawrence from Dangerous Fellows. The problem is that When I was originally fleshing out the characters I wanted to make each of them a different nationality (Because they need to look like they have 0 things in common but there is a secret linking them together on a global scale) and I had planned the yandere as Chinese American (2nd generation immigrant with Chinese speaking parents).
My co author who has recently joined in says this will be recieved poorly because of racist or xenophobic connotations and wants to make him Western European because that'll look better.
I wanted to ask advice on this, is there a such a negative connotation linking Asians/the Asian diaspora/Chinese people and Yandere's? I'm not sure since in most of the Yandere content I've consumed the nationality is not integral to the plot much. I wouldn't want to offend anyone.
