Anton Petrov (starring Martin Paunov)

He is extremely honest and meticulous and he thinks that the answers of all the questions of life lie in science. He feels unappreciated but does not complain about it – instead, he builds a world of his own where he feels invincible.

Tony does not lose his temper easily, he is calm and composed. He has only one weakness – his mouse Marie Curie.
Raya Ivanova (starring Zornitsa Ivanova)
Raya is eight as well and she is Tony’s neighbor. Her parents are rich, they travel all the time or go on vacations, so there’s always someone else to take care of her.

Her parents have enrolled her in the School of Dance because she can spend her energy there and perform in public. Raya is energetic, resourceful, she likes to be at the center of attention. Her desire to be noticed pushes her to break the rules and do mischiefs. She thinks she can get away with anything. Punishments do not scare her, she is a good negotiator.
