Although learning is a tense stage, I think it will still affect learning and feel inferior because I have no hobbies and specialties.
You can write a letter of guarantee to your parents: "I will learn dance voluntarily, and I will study hard for another two months." I am willing to accept punishment if my academic performance drops. I will never refute my parents' words again, and I will be obedient. "
If you can do it, of course they will agree.
Just try it. I am also a mother and daughter. I promise, I will agree.
