Erythrophobia

Kaeya fears Diluc's vermillion eyes. He has ever since the other man returned to Mondstadt 2 years ago. He ignored it at the time, hoping it was a stupid irrational fear that would fade.

It hasn't though--- If anything, he thinks he's gotten worse in the last couple of months. Even just the color red is making him do a double-take every time it comes into his vision. He feels his perfected mask is slipping and he doesn't know how to fix it.

He can only hope that it isn't too noticable.

Meanwhile, Diluc wants to reconcile. The only issue is, he has no idea how to and Kaeya has been acting strange.

He wants to figure him out.
