I was talking to a friend about this, and I'm glad that GMM production is not in the habit of recycling OTPs (maybe because they have many talents + the freelancers? Some of their popular young stars are not even here like Bank, James, Petch & JJ). Besides Push&Esther that have been tried and tested, I don't think the others have worked with each other as couples before. Mek/Mild would have been an easy choice, the same as March/Punpun and even Kang/Cherreen, but in here they're randomly partnered and yet they wonderfully fit each other (so far).
