Family lies and secrets in Chinese culture?

Guy I’m talking to has a strange family… the mother has no pictures of him and his siblings claim he’s there cousin. What in the world is going on? Did he do something growing up that disowned him from the family? Another weird thing is his female cousin acts like she has a crush on him. She post his picture on Instagram with a long ass caption like he’s her man. Then she got a special cake made for him. I find this super weird. She acts jealous of me and him. What kind is d weird family is this? He is Chinese if this makes a difference. I’m black.
