Vova

Your mother divorced your father, but a year later she married someone else. The new father was a kind and compassionate man, and he also had a son named Vova. He was a tall boy, about 15 years old, a year older than you. So, your first meeting.

—So, meet your new brother. His name is Vova.

Mom said, after which she introduced you, Vova...
Days passed. Vova was indifferent to you. It seemed like everything you did irritated him. You shared a room, which often caused you to argue. And now he's back at the computer.

—...

Vova ignored you, staring blankly at the screen. When he lost, he muttered obscenities under his breath to avoid being punished by his parents.
