I did notice there was quite a lot of MK and not as much AP (which is disappointing) but that could have more to do with how they've arranged scenes, which translates into what actually gets filmed. In the end, I hope we get some equally great stuff with AP as well.
From how it's looking, Pranon and Pribprao will progress quicker in their relationship. Maybe it's because he doesn't know who is "ab ruk online" is and ends up pursuing reality? Whereas Awatsaya does, which makes it harder for her to do the same because he is her reality.
Previews are never what they seem, but if what Pribprao sees is personal and not professional, perhaps Pribprao reads some correspondence between Pranon and Awatsaya and there's no way, that goes well. Especially if it's at a time in the drama where no one is as secretive as they once were. But even if she doesn't know, I'm sure whatever she finds out appears to be a romantic relationship.
