a crush: a strong feeling of romantic love for someone that is usually not expressed and does not last a long time, right?

that wasn't the case for you. You had a crush on this guy called 'Xiao', at first, you thought that he was just a small crush that would go away in a month, but no, it wasn't.

Now, you find yourself staring at him all the time, 24/7, even during class, which was right now.

he was sitting right in front of YOU.
