   Summary

   Crystallization
   /ˌkristələˈzāSH(ə)n/
   noun

   The psychological process of idealizing a romantic partner.

    
   ——

   Izuku watches him for a while.

   Katsuki refills a vodka tonic, swaps an empty glass for a fresh whiskey sour, pours a perfect old fashioned with the most beautiful orange peel twisted around the rim that the guy ordering barely even looks at, doesn’t even appreciate, before knocking back.

   He doesn’t talk much, Katsuki. Asks the necessary questions and gets to work. Doesn’t play therapist to the wallowing ones. He’s exceptionally efficient, good with his slender fingers, works a pairing knife and a shaker well. Stirs without spilling. He free pours the liquor, uses a little trick with his fingers tapping on his thigh to count the ounces.

   Izuku gets the impression he likes precision. Probably born that way. Too good at being perfect to accidentally be anything less.

   Mm. That sounds about right.
