I like a girl. Today, she finished the exam. I texted her "Have you finished the exam?" When will you go back to school? Send me a message when you arrive.

If you only have this short message, you can't see anything. You can have more contact. If you like it, go for it. Forget about hope. Look at this short message she sent you back. Should be a very careful girl. You can start by caring about her carefully and then take your time. Since we can meet often, there should be more hope for development.
