4.Everything is warmth
作詞：SHIN
作曲：SHIN
TRUST between us.
Our trust,
KINDNESS between us.
Our kindness,
FLAME between us.
Our flame,
WARMTH between us.
Our warmth,
Woo…Everything is warmth,
We, two create our future
We share success and mistakes
That makes us happy
Other thing would for us later
Let's share this moment
that we've been waiting for
It's not good to carry on burden
We will Forget tears…
