Wth is going on, I don't understand shit

What don’t you understand?

The way that the story going back and forth, i don't even know anymore when it just his imagination or reality

Maybe I'm not paying attention enough...

Yeah it’s a bit confusing and him seeing things was throwing me off too. Usually the fake Uke didn’t have a shirt on. And the flashbacks aren’t defined enough so you gotta really pay attention and I even had to scroll back a few times.
