666 club certainly mitigates the need for a good personality, but a good personality and a nice pair of shoes can help you land a 7 and above.
I used to hangout with several providers (still visit them in Jersey every now and then for coffee) and they all agree that you have to funny if you aren't KR or CH to overcome the language barrier. At the end of the day, they are human...their base emotional needs trumps their desire for Off White and Gucci. Obviously there are outliers in the pool of prospects, but my G, if you want a girl that is decked out in Gucci then you clearly dgaf about personality and probably aren't trying to get hitched. In that case your money is better spent at NYAW or AL/PP/PH/GGR/KKP.
That being said, if you are CH/KR or even JP, at least 5'10, stable income (if you hobby I imagine you do)...holla. I know at least 3 noonas that really want to get married. They don't want to marry me because I'm a 90's baby, just be okay with the idea that I will be her cute little brother for the rest of your relationship.
