Japanese Lyrics
優しくされるとちょっと 優しくなるの
不安な目をされると 不安になるの
段々 You’re Loving Me 段々 I’m Loving You
連鎖しくて感情のラリー
１＋１が２になる関係なんかじゃ満足できない だから
等身大よりちょっぴり大きな愛 手渡して掛け算中
Baby Ding-Dong 広がるChain Reaction
受け取った愛でCh-Changing My Mind
から差し出す愛でCh-Changing Your Mind
愛が愛を呼ぶChain Reaction
素直な想いを聞くと 素直になるの
駆け引きはしないで ずる賢くなっちゃう
段々 You’re Loving Me 段々 I’m Loving You
永遠の感情のラリー
いつか世界も変えてしまうわ あなたのハートが０じゃないなら
等身大よりちょっぴり大きな愛 リレーして掛け算中
Baby Ding-Dong 広がるChain Reaction
受け取った愛でCh-Changing My Mind
から差し出す愛でCh-Changing Your Mind
愛が愛を呼ぶChain Reaction
手放す勇気のない（Oh Baby）
せまいココロに（Are You Ready?）
仕舞えるサイズのシアワセは小さい
ヒトカラヒトヘ
Loveという名のVirusが
伝染してAll Over The World そうほら
ヒトカラヒトカラヒトカラヒトヘ
Baby Ding-Dong 広がるChain Reaction
受け取った愛でCh-Changing My Mind
から差し出す愛でCh-Changing Your Mind
愛が愛を呼ぶChain Reaction
Translation
If you’re treated kindly, will you become a little kinder?
If you’re looked at with worried eyes, will you become worried?
Gradually You're Loving Me, Gradually I'm Loving You
Chaining together a rally of emotions
I can't be satisfied with a 1+1 equals 2 relationship, so
Surrender to this multiplying love that’s a little larger than life
Baby Ding-Dong, the spreading Chain Reaction
Ch-Changing My Mind with the love I received
Ch-Changing Your Mind from the love I present
Love calls out to love, it’s a Chain Reaction
If asked for your honest feelings, will you be honest?
Don’t play games, you'll just become sly
Gradually You're Loving Me, Gradually I'm Loving You
A rally of eternal emotions
Someday the world will also change; if your heart isn't zero
Relay this multiplying love that’s a little larger than life
Baby Ding-Dong, the spreading Chain Reaction
Ch-Changing My Mind with the love I received
Ch-Changing Your Mind from the love I present
Love calls out to love, it’s a Chain Reaction
Let go of the cowardice (Oh Baby)
Within the confined heart (Are You Ready?)
The size of happiness that can end is small
From person to person
The Virus called Love
Is infecting All Over The World; so, look
From person to person to person to person
Baby Ding-Dong, the spreading Chain Reaction
Ch-Changing My Mind with the love I received
Ch-Changing Your Mind from the love I present
Love calls out to love, it’s a Chain Reaction
