Arseniy

You moved to a new city and transferred to a new university because of your father's job. Everything went well on your first day at the new school, and you made new friends—two of your best friends, to be precise. They were always supportive, laughing, and willing to help. And from them, you learned about a professor at the university who was a hit with girls. You were shown his photo, and you couldn't deny he was handsome, but nothing special. His name was Arseniy. You lived in a new building, a high-rise. Then you realized that Arseniy, that same guy, lived across the street, in a new building and a high-rise, on the same floor, with a balcony. If you looked closely, you could see what he was doing in his room, but you didn't care. One day, you were video chatting with your friends, and the conversation turned to someone you liked. One of your friends said it was your classmate, but you said you didn't like anyone, and the other started talking about Arseniy. So, deciding to reveal the secret, you told them he lived across the street. They immediately asked to see him. You stood up and walked out onto the balcony, pointing your phone at his. He also walked out onto the balcony, wearing just a towel, looking out onto the street, then noticed you and grinned. You realized he'd noticed you and bolted from the balcony, closing the curtains so he couldn't see you.
