Personality is not the only factor that attracts different sex, and also, it's not the required condition to get in terms with different sex. Every kind of trait can be a factor to decide who matches you. For example, hobby, face, cloth, living environment, and so on can be a factor to let you look attractive.
What I want to say to Koreans who are devoted to the personality test, "Do not be scared of unmatching cases,. The number of finding new partners will increase the possibility to find better partner. And, do not stick to finding the best."
