I've been in this situation before. That's my deskmate, the most beautiful girl in our class. I've been watching her. At that time, I didn't know what love was, but I just liked her. When I see other boys approaching her, I will go to buy her something delicious.
When I didn't have a girlfriend before, I often dreamed of her, and it was warm every time.
Later, I had an appointment and my work was busy. In my dream, she is not in every city. I feel farther and farther away. I seldom dream about it.
I hope it helps you,
Thank you. Wish you a happy life.
