It’s cute that you like Morning Musume so much that you want to sing and dance like them in public, but may I offer you a bit of cautionary advice?

1. Your performance was uploaded to Youtube with the title "Shock! 10-year-old lolita in a sailor suit". You may not understand why this is a problem, but you should make sure you've got a trustworthy adult with you when you go out singing.
2. Please, however much you admire Morning Musume and wish to emulate them, ignore their fashion sense. You'll thank me later.
