The story features the lead character Morinaka Ryo (Matsuzaka)who is bored with his life as an university student and works without an aim in his part-time job at a bar. One day, his friend from junior high Tajima Shinya who works as a host, brings his customer Midou Shizuka to the bar where Ryo works at. Although Ryo is disinterested in love and women, he accepts the challenge by Shizuka to work at the secret members-only boys' club "Le Club Passion" which she owns. Although Ryo is at a loss as to what to do at first, he gradually comes to realise the depth and strength of the desires hidden in the female customers he comes across and finds meaning in his job as a call boy. In addition, he finds himself falling for Shizuka who is much older than him.
Matsuzaka who turned 29 on 17 October, commented that acting in the stage play version of "Shounen" last year was a huge event in his career and he thought on the last day of the performance that he might never get to do something like this again and immerse himself so fully into a character. As such, when he got the offer to act in the movie, he was worried at first but hoped to be able to show things in the movie which he couldn't do in the stage play. Matsuzaka also revealed that the director had told him before the filming that the making of the movie version was like a finale to the adaptation of Ishida's novel. Now that the filming had wrapped up, he finally understood what the director meant especially after he had devoted himself fully to the portrayal of his character. As such, he hoped that women in particular should watch this movie.
"Shounen" will be shown in cinemas from spring 2018.
