What was she supposed to do… Avina chose martial arts because she was afraid of getting hurt again, and although it was possible to be hurt in this modern world, she regretted not taking the singing skill.

It's like having the option to choose between a cookie and brownie, both being delicious. You choose a cookie and thought you can enjoy a delicious cookie because you chose it, but then you found out there was a million dollars to the person who can give away a brownie. Now what.

It's a million dollars!!
