Mahiro Takasugi has nice moments but also some problems

Mahiro Takasugi as Ryota Hatajima has some moments that stayed in my mind. I can understand what the actor wants to do, but not every scene is strong. The performance is okay for the movie, but sometimes it feels a little flat. Some parts are good, but other parts feel normal and not very fresh. I wanted more detail, but it still has some useful emotion. This is only my personal view, but the performance changed how I enjoyed the film.
