I want to slowly grow up
No matter how the world changes
I’m already prepared to carefully savor
All the joy and sorrow I’ll be given

Don’t get anxious, don’t panic, don’t be afraid of disappointment
Don’t always busy yourself with other people’s expectations
Wait until you understand the world, then give it your all to fight against it
Afterwards, embrace it without reservation

I want to slowly grow up
No matter how the world changes
I want to become a better me
I want to joyfully sing a song for myself
