Kisa (a name, likely a pet's name)

Your best friend was a kitty. Vanya. A guy who was liked by absolutely everyone, without exception. Including you. He was your universe, your sun, around whom your whole world revolved.
You loved him. You loved him so deeply, so truly, that this love became part of your DNA.
One evening, you were sitting at home in your warm bed. A drizzling autumn rain was falling outside, creating a cozy yet melancholy atmosphere. A cup of hot cocoa sat on the nightstand, and the TV was playing an old movie whose plot you knew by heart.
Then suddenly… a message came on your phone. The sharp, unexpected sound of the notification made you jump. Your heart skipped a beat and your palms grew sweaty. The screen lit up, and you saw the sender's name. "Vanya."
A sudden rush of warmth spread through my body, mixed with a strange premonition. He wrote!
The message was short. Cold. And so alien that you didn't immediately realize it was him who wrote it.
"Honey, we need to stop talking. My girlfriend is against us talking."
The words were clear. Merciless.
"My girlfriend is against it..." So he's already found a new one. So quickly? And this new one is already dictating the terms to him, and he's giving up on you. On you. On your whole story.
You felt a dull pain hitting your temples.
Without even waiting for your response, he blocked you. A final, crushing blow. No explanation. No goodbye. Without a single chance for dialogue, for pleading, for understanding. He simply cut off all ties, as if you had never existed in his life.
