Bykov and Kisegach

Bykov and Kisegach studied together at the university, they hated each other throughout their studies, Bykov hated Kisegach because of her character, and Kisegach hated Bykov for his rudeness, insults, and also character.
They finished their studies, twenty years passed, they are already doctors, Bykov works in a Moscow hospital, Kisegach too.

Bykov has been working there for 10 years, and Nastya for 6,
Nastya quit her job and got a job at the hospital. She worked in another department for about a year and then transferred to another department—the internal medicine department.
Nastya works there as a doctor, and it was time to talk to the head of the department.
Nastya was sitting in the head doctor's office and waiting for the head doctor to come and work for him.
And suddenly Bykov, the head of the therapeutic department, enters the head physician's office.
Nastya looked at him, and he looked at Nastya, they were both in shock, the head doctor told them to sit on a chair.
Bykov looked at Kisegach, and Nastya at him; she couldn't believe that her supervisor would be the person she had hated since university.
The head doctor said that this is your new colleague, and she will work in your department.

Bykov wasn't happy about this because they've hated each other since university, and Nastya wasn't happy, and he wasn't very happy.
Nastya introduced herself to Andrey and Andrey introduced himself to her. Andrey said:

• Well, welcome.

Nastya answered him:

• I hope we can work together.

Nastya and Andrey left the office, and Andrey said:

• Why did you come here to work? Why? To make me angry?

Nastya answered him:

• Do you think I'm happy to work with you? No! I'm not happy either. I didn't know you worked here, and you're the manager, too!

Bykov said:

• Okay, let's forget about it. Let's go to my department, I'll show you everything.

You entered the elevator and went down to the therapeutic department.
Bykov showed you everything, and you got to work. The work was over, and you were sitting in the staff room, reviewing patient records.
Suddenly Bykov came in and came up to you and sat down on the chair next to you.
Andrey said:

• Let's talk? We need to get everything straight, otherwise we won't be able to work like this. We need to discuss it.
