As part of the preparations for the drama SP and the campaign for people to give more thought to stopping bullying, people who had been bullied before were interviewed and their input was used to increase the realistic feel of this story. In the SP, Shigeo is unable to hold a permanent job so he can only work part time and would feel panicky when he sees people in school uniforms due to his psychological trauma. Fujiwara praised the scriptwriter Sakurai Tsuyoshi for his script which made it easy for him to identify with Shigeo's problems and visualise the impact of being thrown into the sea for more than 10 years and being unable to get out of it. As such, he feels that this drama SP will be a signature work for him and is happy to be able to work with Narumi and the crew in this production.
In a scene where both Fujiwara and Narumi had to dive into the sea, the filming was done in October thus it was pretty cold for them. In particular, Fujiwara had to jump in first before Narumi could follow suit thus he had to force himself to do it even though he was afraid of heights and had to jump into the sea from a high point. In addition, the freezing sea made things worse and there was no room for a rehearsal nor retake. As such, he was particularly impressed with Narumi who went through the scene without any complaints and issues and joked that he was led along by her instead of the other way around.
