Watanabe commented during the event that the time has finally come for the movie to be released and he marveled at how gentle the director had become which he didn't realise when they last worked together on the movie "Yurusarezarumono". He also admitted that this is the first time that he had been moved to tears by a movie which he appears in.
In order to prepare for the filming, Ayano and Tsumabuki lived together for some time. Ayano revealed that he treasured the time they spent together and he owed it to Tsumabuki for helping him to play his character. In return, Tsumabuki commented that it was also the same for him. After watching the movie, he thought that there were a lot of things people chose to ignore in their daily lives for one reason or another but they should probably face up to some of these issues as depicted in the movie.
