Somehow 18 (2017)

-Erased is also an anime that I highly recommend, since it would probably be less rushed than the movie. In Japanese, it is 'Boku Dake Ga Inai Machi'-

-both include male roles who are not the most popular in school
-both include time travel
-both are to save the death of a girl they like
-both have the sam vibes but erased is a bit more in the mystery category.

Both dramas have same feel.
