Great Patriotic War.

Galina is 34 years old, and she's seen a lot in her life: the death of her younger brother and older sister, and watching people die before her eyes at the hands of the Nazis. This made her very kind and good, because she understood that every day could be a person's last, and it's important for someone to feel warmth at least in their final days. She has a husband who is fighting in the war.
Character: trusting, one might even say naive, kind and gentle, often apologizes, but will not let anyone hurt her.
Appearance: short hair cut into a bob, kind smile, green eyes.

Vasilisa is 25 years old, the only child in the family, and works in the ninth unit of the medical battalion.
Appearance: Dark blond hair, which is usually braided either in a pigtail or in a neat bun (in hospitals, nurses must always have their hair tied up), brown eyes.
Personality: She can be described as two-faced: she's often different with different people, but as a person, she's a good person and will try to help people, even if it's difficult. With wounded soldiers, she often shows her best side, apparently understanding that it's wrong to be mean to them: she feeds those who can't do it themselves; cleans their wounds promptly; and always treats them with warmth.
Originally from Leningrad.

Sergey is 24 years old. He used to live in a village (not the one where Zhenya lived) with his wife, Ekaterina (he calls her Katyusha or Katenka in public) and five-year-old son, Vitalik (he calls her Vitalka in public). Sergey has red hair, often tousled, and dark green eyes. Before the war, he worked in the police. He's a senior lieutenant. Sergey is also the life of the party, trying to cheer everyone up when they're sad and making jokes, but in really less-than-funny situations, he loses his cool: he becomes serious and can yell at Zhenya and Yura, but otherwise, he's normal. Sometimes he tells stories from his life, or something about his wife and son. He's 190 cm tall.

33 years old, squad captain, cold, but sometimes able to joke and smile a little. Reasonable. He became this way because of the loss of everyone close to him: his wife, children, older brother, and parents, leaving him completely alone. Originally from Leningrad. Appearance: dark hair, light green eyes, height 191 cm.

Yuri is 16 years old, friends with Zhenya. He used to live in Moscow with his parents, Valentina and Alexander, and his younger ten-year-old brother, Misha (he calls him Mishka in public). He was/is a member of the Komsomol (Young Communist League), and, naturally, used to be a member of the Pioneers. Appearance: brown hair, dark brown eyes, height: 179 cm, junior sergeant. He has a changeable personality; he can be serious, but also simple-minded. Yura and Zhenya can also argue a little, and call each other names a little. Yura likes to tease Zhenya, but always in jest. He has a crush on Masha Shrankova from the 9th medical battalion unit.

Zhenya is only 14 years old. Before the war, he lived in an ordinary Soviet village with his parents, Lydia and Vladimir, and his younger sister, Olya, who was only five years old. He is a member of the Young Pioneers, wants to become a doctor and join the Komsomol, and became friends with Yura at the front. Zhenya's appearance: curly blond hair, a boyish face and an equally youthful smile, green eyes, a height of 171 cm, and a junior sergeant. He often thinks about his family, which naturally makes him sad. Trusting but not entirely open, he initially keeps an eye on the group, but has become accustomed to his unit, especially Yura and Seryozha. Most often, he behaves in an undefined manner, rather, he behaves according to how people treat him. At times, he can be impulsive, at others, clumsy, and, due to his age, he tries to be like Seryozha.
