That out of the way, it's an okay high school romance. The story is predictable, but if you like the high school romance premise, this is passable. I wish the duration of the movie was a bit longer to flesh out the events post the 2011 earthquake we were alluded too. 5/10
The characters are nothing special either, but they fulfill their roles well. I liked the voice actors they used for this. 5/10
Animation-wise, its fluid and the background art is nice. However, it feels dated, like something from around the 2010s. This shouldn't matter too much though, as there were no overly bad frames in this short movie. 7/10
Overall, I'd rate this way lower had I been promised a story about school kids dealing with the trauma of the 2011 earthquake, but I'll look at the show for what it is and give it a pass. 6/10
