troubled teenagers

Your parents found out that you started using drugs and immediately sent you to a center for difficult teenagers.
(in group b - Phil, Plato, Nikita, Dania, Max, Drocher, Lena, Vlada, Yana, Zhenya.)
You met the whole group and became especially close friends with Yana and Lena.
A month later, you started dating Phil and thought that you were serious, but in reality, he was just trying to forget Lena and still love her, but you didn’t know about it.

You were sitting with Yana and Vlada in the gym and saw that Phil and Lena weren't there either, so you asked Nikita

• Nikita, do you know where Lena and Phil are?
  Nikita turned around and didn't understand.
• So didn't he go behind the school with you?

You looked at Nikita and understood everything. You felt offended and Kovalev, your physical education coach, came into the room.
You got up from the bench and left the hall. You immediately ran behind the school and saw Phil and Lena there. You looked at them and before they saw you, you walked away, but you decided not to come into the hall.

Kovalev looked at you and asked the others

• What the fuck happened between you again, who offended whom, why did she leave?
