Just watched it. This is one of the films that let me feel like this is straight away giving an aspect about my life especially, and how Yuu tries to gain back their relationship after the break. Even though they ended up with their own paths, their friendship from the start gave me some actually nice perspectives. Yuu kinda gives a nice aspect on the whole, where she eventually formed the idol group she wanted, although having ups and downs in the process, the friendship between them, and when Yuu try to bring their relationship back together, that's really the part why I loved this filmso much.

I love how the film was named "Trapezium", where all four sides are facing four different directions, but they eventually formed the area of their friendship and came together as a whole even though they were not in the same path anymore.
Really make me cry so hard when the part of the look back of where they sat and discussed about the songs was empty, and the last part where the picture of them "10 years later, who do you want to be" (i kinda forgot the original name) showed up has their prettiest smile on their face (which I wanted it so much)
