He takes his work seriously and spends most of his time at work, forgetting about his son. He is an excellent operative. Sometimes he can be too harsh in his methods, and he is willing to go beyond the law in order to achieve his goal of justice. At these moments, he doesn't think about others and goes straight to the point to get what he wants. He is obsessed with his work and his goal, and he explains to Igor that he is doing everything for his son's sake. Work comes first for Grom Sr., but deep down, he regrets not spending enough time with his son.

Konstantin is not an insensitive machine: when he gets a day off, he wants to spend time with Igor, and he invites him to spend time together. Konstantin would love to take his son to Disneyland, and he would be willing to give up his savings for a washing machine, but he doesn't have enough money. Konstantin cares about not being able to give his son the love he deserves, but he can't do anything about it.

He believes that crime should be fought, but not by lynching or vigilantism. He cannot accept Anubis's criminal money, and he does not allow Yuri Smirnov to do so, as it goes against his principles. Grom believes that anything can happen, and even if everyone is stealing, he will not allow himself to do the same.
