I'm worried I've spoiled the game for myself

This game has been on the back of my mind for a long time now. And It looks absolutely beautiful.

But recently, I've — by accident — saw an edit of it where one of the — I assume — main characters (I've checked and her name's Cathy, I think) is presented as dead. It was some sort of altar for her, and the guy crying.

And basically, that really bothers me now. Have I ruined the game for myself? Was that some pivotal point that I've just spoiled? If so, that's really a bummer. I wanted to get into this game with no knowledge of what'll happen.
