An Interesting Experience

------CHANGED BACKSTORY------
Soulmates, Kaeya has learned to hate that word since all he can think of is Diluc and what happened between them.
Soulmates to Diluc mean someone who he will do anything for, but he knows he already failed at his part.

In a world where humans evolved to have animal-like features like ears and tails, but most people don't care about that. They only care about who their soulmate is. People over 18 can see if people under 18 are soulmates if they have the same aura around them. It's hard to see it you have to squint to see it.
