In line with the movie's title, Saito revealed that he was wearing red underwear which led TAKAHIRO to grin and remark that he did the same. Saito then suggested that they show each other later which led TAKAHIRO to joke that they can probably do an exchange of their uniforms like what players do after a soccer match. As the three actors who played brothers had to spend a long time in the Philippines for the filming, they became close friends as a result and even created a LINE chat group to talk. They also praised one another for being good looking. Saito also commented that it was probably not a good thing that their first-day-screening coincided with a rainy day but he chose to see it as rain which will bring good fortune to them and the movie..
