My assumption is that Jhin has something to do with dreams and/or nightmares. All of the aforementione characters have a lot of pride (that they dream of), and a lot to fear (within their nightmares).

Garen is revered among the Demacian people, but he presumably fears falling out of grace with them if he succumbs to his feelings for Katarina.

Zed is the proud leader of the Order of Shadows, but he fears the shadows consuming him if he loses control.

Sona is proud of her music, but fears losing the attention and grandeur her talents bring her.

Vi is proud of her power and position on the force, but fears losing that power and being ousted because of her Zaunite background.

But that's just a theory. A game theory.
