This was probably just a joke and I'm being an idiot but, I think it's a metaphor for the evil guy and the uke's relationship, where the uke is the fish and crazy is trying to isolate him because he's precious, rare and valuable or some shit. And then the fish eating itself is supposed to symbolize how such a deprived environment can cause a person to corrode away and lose whatever made them special, or that the environment can cause a person to want to… stop existing(?). Idk, that’s what I interpreted, but it’s probably not cannibalism, haha.

So I learned that when fishes eat their tail it means they are either stressed, hungry or lonely..... it symbolized someone in a toxic relationship, where they where being isolated and when said to be treated preciously is just taking a toll on them putting them to verge of stress and wanting to escape.....I'm not so sure about this, but this just what I understood
yall im probably being dumb- but the fish eating its own tail at the end BETTER NOT BE ANY INDICATION OF SELF CANNIBALISM OR IMMA ScREAM
