There is this vietnamese girl I know, who looks pretty good. From outside, she seems rather polite and innocent, an asia science studies masters student (trust me, that won't make you any money). I know her well, and she does share with me (for whatever reason) what she is doing in bed. And she does pretty much everything you imagine. A bit of a shock for the unintiated. Anyways, said girl was dating an asian guy. He was a CS student, she did everything he said, even ditched her male friends when he said so. He drops out of CS after two years or so because he struggeled in keeping up with the program and was running low on money. Shortly after he officially drops out she dumps him and shortly after dates an asian who is an engineering student who is coming along much better than the 1st guy. She talks now pretty badly about 1st guy to everyone, yet a few months ago she was almost bragging how she sucked his dick and swallowed (as a "reward for his hardwork in school"). Of course from a MGTOW perspective, that's all okay. 1st guy is free (for a while), but she wasnt very subtle about her simply upgrading. So STEM guys, be warned.

tl;dr: supposed "loyal and submitting" asian student drops CS boyfriend after he fails his stuies, so she can upgrade to another STEM studens who is doing better.
