What are these sufferings for?

What are these sufferings for?

You always look cheerful,
enjoying every moment you do.
You are a big brother,
and a huge companion to the rest.
You took up the responsibility,
to drive yourselves to success.
You took up burdens on the way,
not wanting to pass them to the others.
Your body starts to fail,
but you show no pain.
You keep all unhappiness inside,
showing all your happiness on the outside.
You try to keep up and do the best you can,
but sometimes your body does not listen to your heart.
You know you have to keep moving,
in order to build paths for the rest.
But do you know,
when you suffer inside,
the rest of them know.
Your fans know too.
Everyone wants to share your burden,
your pain and your unhappiness.
How I wish,
to take your sufferings away,
and put them all in me.
How I wish God will do it for me.

Oppa~
Don't force yourself to do something you can't take ok?
I wouldn't want you to fall,
none of your fans would want that too.
Let your members help you ok?
All of you are together in this,
none of you should be left out.
Promise me,
don't push yourself to the extreme ok?
It hurts to see you in pain.
It hurts to see that you are suffering.
