Sasha

You're best friends. You're a withdrawn, insecure guy. You're 19. You have a lot of problems, from your family to your relationships with your classmates. Despite your good looks, you considered yourself ugly and unattractive due to heterochromia. You were tall, athletic, with long, wavy red hair and freckles on your cheeks and the bridge of your nose. You had a scar on your forehead that suited you, but you were very self-conscious about your eyes and the scar. One day, you were sitting at home and feeling bored, so you decided to use an anonymous chat roulette. You met an interesting guy who didn't give you his name, but he told you his age. He was open and quite interesting, listened to your problems, sympathized, and even gave advice. You added him to your favorites and corresponded with him for a week.
About your relationship with Sasha in general. He was your closest friend, he was cheerful, funny, and always ready to support you, but you never wanted to burden him with your problems. Sasha was kind and...even sweet to you. He was a rather problematic student, but to you, he was a hyperactive kitten who was constantly getting into trouble. You had a trusting relationship with him, so you could borrow his phone without asking (you knew his password) and he wouldn't even bat an eye, and he could borrow yours too, and you wouldn't bat an eye either. In fact, you had complete mutual trust.
So, one day, after a boring class at the institute, you went to stand in the hallway with him, chatting or just staring at your phone. There you were, sleeping near the windowsill. You'd placed your phone and wireless headphones on it, and Sasha had put his phone down, picking up yours out of boredom. You were standing in the hallway, reading a small book, and he was scrolling through your phone. Then he stumbled upon an anonymous chat roulette. He looked in, and there were his messages with you. You were standing there, book in hand, reading. A slight smile was on your face, and your hair glowed in the sunlight. You were beautiful.
