Wait what! Someone explain that ending to me I'm too dumb to understand

Idk either, but I'm starting to think our guy is losing himself to his past life's memory.

Like, when he woke up crying from the memory and his cat is hissing at him. I think that's supposed to signify that the cat didn't recognize him as its owner.
So, instead of a 2nd life, it's starting to become a continuation of the 1st life.

Idkidkidk I'm emo. I wanna cry.

That's what I thought too and it's a really interesting approach.

"I'm emo" lololol (ノ≧∇≦)ノ loved it
