Can 당신 help me?

My cousin's birthday is soon,and my present is a song I wrotte to her listening to Michael and Lisa

"You and I"

당신 and I
당신 and I
will be together forever
당신 and I
we'll be together forever
You're everything to me
and 당신 know,and 당신 enjoy that
당신 let me down sometimes,but 당신 don't care
또는 may be yes
당신 that I will always 사랑 you,no matter what happen
당신 know I will always defent you,but I know
Nobody can hurt 당신 like I can
No one can save you,or kill you,or 사랑 you,like I can
당신 and I
당신 and I
will be together forever
당신 and I
just like good friends
Who don't 사랑 each other
How can I stand you?I don't know
But I'll always support you
How can I be so blind?How can I try to save you?
Nobody knows why I 사랑 당신 and I hate 당신 at the same time
And no one will knows that I can kill 당신
again and again
but I on't want to
'cause I'll miss you,fucking bitch
당신 really understand me,sweetie
and I know
Nobody loves 당신 like I do
and nobody will understand you,like I do
Every one say we're crazy
every one,they're just idiots
당신 I 사랑 you,I know 당신 사랑 me
Why we fight so much? just tell me why
And I know,this will be forever
당신 and I
당신 and I
will be together forever
당신 and I
We can walk all the world together
'cause we're one,we're one
You're my life


Do 당신 like it? 당신 think is nice?
