Why am I standing alone in the twilight
Let me go,no more lonely nights
I take a deep breath under the bazy sky
Feel like losing, but it's gonna be alright

Break through the night, go and try to fight
Don't be afraid,now is the time

Be alive,take it
I surely feel my heartbeat
There's no limit to my reach
I say good-bye to my tears that I don't need
So believe in my dream

Don't look back to the sorrow I left behind
Here's my real intention I hide
I wish you were here, and so just right by my side
Need to be strong enough to swallow my pride

I have been looking for my onw style
Don't give it up,here comes the life

Be alive,take it
I have leained a great deal
Brighten our sweet memories
Hope the
