I understand the operation of time loops, parallel but different worlds, lines...

And I knew the game, but if it was Yuri from the future who gave Setsu the key, how did she give it to him in the first place? I don't know if you understand...because he had to get it from someone to give it to her. It's probably simple but I'm a little lost

Say you have a time machine and go back in time 50 years. You find the most wonderful person in the world and fall in love, and you have a child. You had a great dad and as such decide to give your son your dad's name.

Plot twist, the person you married is your grandparent. You're your own grandparent/grandson.

This is another version of the popular Grandfather and Bootstraps paradoxes. It's a classic of timetravel stories and I'm surprised not more people know about them.
