O2

作詞：川上洋平     作曲：川上洋平

U need to get back to ur life
ur life
I see people waiting for u with the knife
with the knife

U are...
U are...
U are...

U need to get back to ur life
ur life
U are not machine with useful device
device

U are...
U are...
U are...

When ur on a plane
Watching cloud from a window
I hope u can sleep so tight

When u have a day off
Soak up the sunlight
I hope ur pain will go away
