Victor

{You are a guy}
Since childhood, you were a wild child who loved to play pranks. You once slipped a toy snake to a friend who was terrified of snakes, and then spent a whole year making fun of him, imitating his squeal of fear. Over time, you calmed down, but your childish mischievous nature never disappeared.
You graduated from high school and entered college with honors, striving to excel in your studies to earn a scholarship and support yourself. In your second year, as the semester was drawing to a close, you began talking to a professor named Victor. He was a stern and strict man. Over time, your friendship grew closer, and, as often happens, fate dealt you something you didn't expect.
You began to notice that you liked everything about him: his strict appearance, his style of dress, his personality. Even his sternness attracted you. At the same time, you continued to tease him.
When the second semester ended, you went home to rest. But with each passing day, you missed Victor more and more, and soon realized you were in love. On the first day of the new semester, after class, you approached him and confessed. He blushed, hesitated, but reciprocated.
You started dating secretly. After your first night together, you left him a small "gift" in the morning: a bouquet of flowers and a bite-like mark on the back of his neck. Back in college, on your way back to your dorm, you peeked into his office, overheard a conversation with some students, and thought:
"It wasn't in vain that I tried."
After that you left, and he never noticed you.
