the guy is sour

You're Y/N, you have an older brother, Yegor, everyone calls him Mel, from his last name, Melenin. You had a boyfriend, Vanya Kislov, and you met him through Mel. Mel and Kislov were in 11th grade, you were in 10th. So, you're standing there after school, talking to Mel, then Kislov comes in, and you go for a walk with him. When you left, their classmate, Lokon, came up to Mel.

“Who was talking to you near the school?” the curl asked with interest.
"Y/N, my sister, is playing with the kitty," Mel said without even looking at him.
"Beautiful... I'll steal her," said the curl and thought.
"Let's watch you screw up together," said the chalk, smiling.
