Interesting story concept and great execution of portraying the events.
I suppose it's open to interpretation, but I wonder what the author's take is on this animation.
I've watched this a few times now, and it's definitely an intense story.
Also, did the main character just inject mouthwash at the end? XD
Anyway, great job all around. I really like the song selections you used as well.
Keep up the great work!
