Anime: Assassination Classroom
Who would've thought an anime about a yellow octopus teaching a class of delinquents to reach their full potential to have the saddest song I ever heard?!
This anime was beautiful. I loved how it was all about the teacher and his students and this song reflects how much his class treasured him. Avoid comments if you haven't seen this anime, because there are spoilers in them e.e
The song starts with the main character singing, then about a couple minutes in the entire class joins in to sing and I lost it ;w;
