Basically, this was what was said in the gcf chapter and for those who cannot see the font, I've rewritten it for you.

This is an open letter
from me to you. . . .

They say that stars are born every billions of years.

And I think this universe gained a super nova with you

At first, a small fire

But soon, you shinee brighter than any super cluster in space

Your smile can light up a planet

Your eyes hold the galaxy

Your beauty is out of this world

Your spirit is made up of
constellations

Your dreams are diamonds

so keep shining, keep dreaming and keep smiling

And never ever lose your light

I love you . . . . happy birthday

Sincerely,
                Jeon Jungkook
