Not to kill your hopes but these are extremely isolated and rare cases, you better invest money in yourself. (or with a lot of money it could be possible, it's the only explanation for this horrible relationship, I don't know, I don't understand the culture of Vietnam)
Being in the world of SIMPS should be temporary, it should not be for life, it is a mistake that should be made like the falls we have when we learn to walk but stop doing so when we are older. Exercise, learn things and detox from this dark world of SIMPS. YOU WILL NEVER FIND HAPPINESS HERE...good luck.
