LIKES:
The cast was good and Takeru Sato as always played his role to perfection. He's good at playing a brooding character. Also I liked his chemistry with the FL, which helped with the emotional scenes. I like the production and cinematography. The scene after the credits finished, felt tacked on, but was needed to not have the viewers revolt. LOL. The songs were okay enough that I didn't have to mute them. I didn't notice any special effects.

DISLIKES:
Distortion on the songs, as if bad editing. It was very noticeable when the girl was singing and very bad during the song that played while the credits of the movie rolled. Not enough development of the storyline during the movie, this should’ve been a series of episodes. That also caused a lack of character depth and made everything seem rushed. Because of the lack of screen time for ML and FL, the heartbreaking moments fell flat, as there was no real connection to show the viewer the depth of their relationship. Maybe that’s why they added an extra moment after the end of the credits, but it felt slapped on like an after-thought. Could've just been bad editing. The writing seemed mashed together, because some of the dialog was lacking. The South Korean version of this movie of the same name, was done in 16 episodes that were 60 minutes each. That show gave enough time for character development, depth and growth, plus a better timed plot and completed storyline. This Japanese version as a movie had so much potential and failed. Not even Takeru Satoh could save this and he's mostly the reason I gave it even a 5/10 rating.

OVERALL:
It's an easy watch and we get to see Takeru Satoh kiss, lol. For someone who never read the manga or seen the 2017 S. Korean version, it could be enjoyable. I wont rewatch it, and am on the fence about recommending it too.
