am i dumb or what???

Two days ago, I was traveling alone on the metro around 9:30 PM. I was listening to my favorite playlist & Arijit Singh's chodh diya started playing. It made me miss my ex sfm so subconsciously I started drawing a heart on metro door & wrote I <3 U (my ex's name is yuvraj, I called him UV) and when i looked into the glass there was a reflection of an okayish looking, well-groomed & dressed boy with a good physique, he was standing beside me. Our eyes met in metro glass & he stared at me weirdly with a scared look in his eyes & left the metro at the next station. I suddenly realized he might have misunderstood that I'm coming on to him

Do you think he got scared & thought of me as a creep?
