--Is there a person you have liked since childhood? He may know it, he may not know it. It is your own business that you like him.
--Is there a person whom you hope to see you and fear that he will see you? You are conflicted and look for his back in the crowd.
--Is there a person who you only dare to look at secretly, during class, after class, and when we say goodbye?
--Is there a person you haven't seen for a long time, but you still dream about him, whisper his name but forget his appearance.
