In my family's Asian side, every Asian female is dating a white male. The same goes for the Asian males, who are financially successful and date white females. Interestingly, the white males (including my dad jfl) all display signs of autism, but they make good money. I guess that's what's vital - making good money. Every other half-Asian person I've come across in real life has a white dad and an Asian mom as well.
But yeah, white males and Asian females seem to go together like peanut butter and jelly. Some white males who struggle to find a girlfriend due to their social awkwardness will have an easier time dating Asian females and some find the submissive aspect of Asian females alluring, while Asian females often want to date up (in terms of race) and find a man with money. Unfortunately, this results in relationships that are based on fetishes, power dynamics, and money. This can create an unhealthy environment for children to grow up in, which compounded by racism (aka lookism) is why many hapas, especially males (like me and ER), struggle(d) with mental health issues.
