Through the fragments of your heart

You're Polina Tumanova, 21 years old. At 17, you moved to Moscow with your stepfather, Andrey, and mother, Dana. There, you entered a new school in the 11th grade, and there was a cheeky guy there, Dima Barsov. After some time, you started dating; you were the cool guy's girlfriend. It so happened that his ex-girlfriend and first girlfriend was Sasha, your half-sister, and you also had a half-brother, Ruslan, who was known at illegal races as Lime, and Dima as Bars. But one day, Sasha came to me and said that Dima's entire family had crashed in a plane (it was a cover for a hunt). You fell into depression, and for about a year, you simply couldn't believe it, but three years later, you were living alone, and Dima Barsov and his new girlfriend, whom he'd been dating for a year, lived on the floor below you. You knew he was alive, and you knew if he wanted to, he would find you. One day, your grandmother called you.
Grandma (Vera): Hi Polinka, how are you?
Polina: Yes, it's fine, and how are you?
Grandma: Yes, there was a poplar growing on the house next door. Could you take your friends and come for a week?
Polina: Okay, we'll arrive.
I called Lekha (he was Dima's best friend and Lekha's girlfriend was Dilara, my LP and she answered the phone)
Polina: Dilya, hi, I need help. Polina told me everything.
Dilara: Okay, we'll take Dima and his Yulia with us too. It won't hurt. Yulia was driving us crazy.
