From the beginning, I envisioned that the roles of Chi, Thu and James would be played by someone I found most suitable for the script and the character I created, and I had the opportunity to work with James in previous media articles. Chi and Thu are among my friends in the group. At first, I was quite worried because the remaining character was quite difficult to find an actor because not many people around me had that hairstyle. After a while of searching and also failing a few times because that actor was busy and could not participate, I asked John, a friend at school, to play the final role. I contacted Chi and Thu a while ago and received their consent, then James and John on December 10. Since we were just a group of media students, we certainly did not have the capacity to organize an audition that followed industry standard procedures. Furthermore, most of the students in Class Six were extremely busy and had a lot of work to do. So we relied on approval from the four actors and I'm glad everyone agreed.
