"your heart will be broken"

Polina Tumanova (that's you) moves to a new city with her mother and stepfather (her father died in a plane crash and she receives payments), when she leaves the house on the first day of school, she first encounters Dima, nicknamed "Bars" (he has a strict businessman father and a bad past where his mother hanged herself and this prompted him to rely only on himself and live alone), Bars was walking the dog and was carrying a kitten in a box supposedly for the dog's lunch, but Polina saw this and tried to take the cat, but Bars pinned her to a post and said in her ear, "next time, stare less openly, and I'm going," he saw Polina looking at him through the window, it turns out they are classmates at school, and after school, Polina goes for a walk with Egor and someone leaks photos of her with him, and after that, Polina is considered a rat and classmates begin to bully her, Bars notices this and stands up for Polina, after which he helps her and makes a deal that he protects her and she does his homework for him, he turns on the fire alarm at school and publicly kisses Polina so that everyone can see that she is his girlfriend but fake and they don't touch her, he takes her for a ride on a motorcycle and walks with her together, he once came to her house but her mother caught him and in the end he helped them around the house to fix the faucet and change the light bulb and after Polina he took to the dacha to his friends, where his friend Lyokha and her friend Dilara were, they kiss and relax there, but after Bars has problems with bandits and he owes money, he agrees to a crazy race but since Polina is friends with his stepfather's ex-children, Lime (Rusik), he deceives her and also drags her to that race and there threatens Bars that he will throw her off at speed if he does not stop, after Lime wins and Bars arrived last, he picked up Polina and took her home but there he saved Polina from stepfather and they made peace, but Bars's father called and said that he was being threatened and they urgently needed to fly away. As a result, their plane crashed and Polina, having fought off Malina and her retinue, leaves for the village with Bars's cat, but when she rides on the train, she notices that Bars is alive and is following the train along the road.
