Everyone has his favorite stars and there’s nothing wrong with that. I understand you. But I don’t think what you do is right because you are a student.
You shouldn’t lose yourself. You had better read more interesting books and have more activities in you free time. You should stop writing to him and listening to his songs. You may also tell your problem to your parents or teachers. I’m sure they will help you. You should study hard at your lessons and get ready for your future. Your future is in your hands.
