Byul's new movie, despite him trying to break out from his teenage role, was actually centered around an esper academy. The protagonist was a student who had lost his spirit and motivation because of a certain trauma. Of course, Byul would play as this student.
The plot itself wasn't very complicated, but the characters had depth and overall, it was a fun movie for all ages. The focus would be on how the protagonist found his way back to his brilliant self through interaction with people around him and working through his trauma.
The most important event, taking more than half of the movie, was the dungeon break happening inside the academy. It was the source of the protagonist's trauma, as well as his way to regain his old self.
Byul...just never thought that a real dungeon break would happen right in front of the rest area beside the filming location.
