In this video clip posted on ichifure twitter today, Kento says that as the cast are all about the same age, they got along well with one another. He feels that this also shows in the movie itself. He really had fun playing the honest, lovable, silly Hase Yuuki. The time he spent with everyone as Hase Yuuki was more enjoyable than anything else.
