Yeah, it carries over to GL too. The pairings usually do fanservice and more than one series together. As for hetero ships, I don't think so. For example, I never saw Earth and Namtam do any fanservice together when they were promoting Ploy's Yearbook. I think for them it's different and that model is only used for BL/GL
I know very little about Thai entertainment but if I remember correctly Nadech and Yaya / Mark and Kimberly were basically a ship for yearsss before becoming engaged/marrying irl. Like they have done several shows together and had brand events and ship work (difference is they also acted with other actors in other dramas in between). If someone knows more, please correct me lol
