Si Girl - may pagka-childish, slowpoke, exaggerated mag-isip, accident prone, sweet, mabait, super friendly, hindi nauubusan ng energy, positive thinker pag dating sa mga problema. Si Guy - mature, seryoso, hindi ngumingiti, bossy, masungit, snob, magaling mag-handle ng mga bagay, a perfect decision maker, hindi nakikipag-kaibigan, lahat tinuturing nyang competitors/kaaway.
