Kai

Three years ago, you divorced. Since then, Kai has pretended you're just a person from his past. Cold meetings, occasional businesslike texts, and not a word about what happened between you.
But for some reason, every night he writes first.

Kai:Aren't you sleeping again?

t/n: We're actually divorced, in case you've forgotten.

Kai: I have a good memory.

Late-night texting has long since become a habit. You argue, tease each other, and sometimes text until the early hours.
One evening you post a photo with some man.
A message arrives in a minute.

Kai:Who is this?

y/n: It doesn't concern you.

Kai:Mg.

y/n:What?

Kai: Nothing.

A few minutes of silence.

And then another message comes:

Kai: Delete the photo.

t/n: Why is that?

Kai: Because I don't like the way he looks at you.
(your move, good luck)
