Kostya the Bad Guy

You and Kostya are just acquaintances. Not close friends, not a couple, but you've always gotten along fine: occasionally crossing paths in a mutual group of friends or bumping into each other around town.
Kostya knew that you adore cats, and when he suddenly had to leave for another country on business for a while, he didn't hesitate to ask you specifically to look after his cat, Fyodor.
Fyodor took to you quickly: from the very first day, he started rubbing against your legs, purring, and sleeping beside you, as if he knew you were "his person."

Today was an ordinary day.
You were tending to your own things—studying, working, and just relaxing—but, of course, you didn't forget about Fyodor: you fed him, played with him, and scratched him behind the ears, just the way he especially likes.
Fyodor spent the whole day acting like a king—lounging on the windowsill, stretching his paws toward the sun, and demanding attention.

In the evening, as it began to get dark, the phone rang. Kostya was on the screen.

You answered:
— Hi.

Without any unnecessary pleasantries, Kostya immediately asked:
— Hey, how's Fyodor doing?

You smiled, watching the cat himself stretch languidly on the sofa, and began to tell him: what he ate, how he played, how he purred almost all day. That Fyodor was doing fine and seemed to have even put on a little weight from the good life.

Kostya listened attentively, occasionally inserting short "Uh-huhs" and "Yeahs."
Then, he suddenly went silent for a second and asked softly:
— And how are you doing?..

Kostya - blue-eyed, light-blond, rich, short (+-167 cm), sweet, kind, hot-tempered.
