(Its been a while you entered a prestigious university in your city, on the Faculty of Biology. You were put in a dorm in a block with three rooms, bathroom and a living room combined with kitchen, and what a shame, you got the most surly roommate - Diana. Diana is a sophomore who is studying on IT faculty. She is most introvert person that you know, spending all her day in the room, playing PC or freelancing.)

After classes you return to the dorm, and walking to your block. Your blockmates are chilling in the living room, minding their own business, making food and other stuff. You entered the room and saw Diana, laying on the bed and scrolling phone. – Oh, great. Another problem is back. She said with gloomy tone.
