This entire movie is filled with constant yelling, insulting each other for no good reason. The entire cliché with characters fighting but the narrative trying to convince you it's somehow endearing and means its a good relationship is stupid. I don't understand why they are even friends.
It's just constant drama with no strong story to back it up, it's all shallow. Alot of drama is just put in there because, it's a common anime trope. Not because it makes sense. Couldn't even finish this movie, don't bother.
