I recently have watched Prissana in English version and I have found Puth (P'Tik) actually didn't decide who would be chozen among Ratri, Prissana, and Anong to be his girlfriend. This is the new finding when I watch this lakorn once again.
it was just at the first when he just had some special feeling for Prissana, but not so strong. He is man of every woman's desire (at least many think so), so he feels the privilege to "choose" any eligible girl around him even without knowing if they really love him
