RADWIMPS - バイ·マイ·サイ
作词：野田洋次郎
作曲：野田洋次郎

Now， just now I know that I’m happy
because you’re here with me
You， just you is what I really need
and all the other thought means nothing to me
’Love’is the word I really need
because all the other word means nothing to me
’Love’is the word I really need because
all the other words just make me tell lies
By my side， by my side， by my side，
stay by my side， by my side
Stay by my side， by my side， by my side，
stay by my side by my side
Now， just now I know that I’m lonely
because you’re away from me
You， about you， about me is about you
and I’ll repeat the same verses over
and over and over again until you’re back to me
’Love’is the word I really need
so all of these affections need a place where to go
’Love’is the word I really need
so please will you come back and kiss on my cheek
By my side， by my side， by my side，
