The movie is gonna be a "Complete Edition" by combining 2gether The series & Still 2gether.
In this version, we will get to see more of Sarawat's point of view on some scenes, such as the story behind their first meeting and the reason why he said: "Keep looking at me like that and I will kiss till you drop."
There will also be "Hidden Scene", which are the new scenes that were filmed to bind the story together.
They will also make a new OST. And the end is gonna be different from the series.
