I remembered, Mark straight up said he likes beautiful girls. Then he added on, "If added with good personality and has good manners, then it's perfect." That's what I remembered. And Nadech said he likes girls who can cook, then they asked him what kind of food he would want his girl to know how to cook, and he said, Lao-Thai food would be great. That's what they said on Ratree Samosorn. Then P'Boy talked about his ideal type on Eislien Butterflies (or whatever, it was hahah I forgot), Mark & Mint went there too, he said he likes girls who's good with fashion, who can dress up well, and have kala taesa (forgot what it means). And Mark said at that event that he likes sweet kind of women.
So basically, he likes sweet and sour kind of girl, with good personality, cute, prim & proper, girls who likes to work out, difficult, and can be selfish. All of his ideal type that he's describing, are basically like Chalida's styles and personality, and character hahaha
