I love this movie and watched it three times. It's by no means a masterpiece, but it's relatable. I love Kento Yamazaki and Elaiza Ikeda (the tall girl from the group of friends) which originally made me want to watch the movie. I'm not a big fan of dramas but this was heartwarming and humorous. I suggest that if you are learning Japanese or just want to watch a Japanese show or film, you should, after watching this one, try and watch Switched which is on Netflix, and Boku wa Mari no Naka (inside Mari) which has episodes on Bilibili.
