それを決めているのは幸せを頬張る君自身。How much happiness do you eat? You decide it is yourself who eats happiness.

今ここから歩き出す。 
未来の種は過去に蒔かれている。 

過去に蓄積されているのは 
あの日やったのかやらなかったのか。 

幸せをどれだけ食べたら幸せか 
それを決めているのは 
幸せを頬張る君自身。 

I will start walking here from now. 
The seeds of the future are planted in the past. 
What has been accumulated in the past 
Did not I do it whether I did that day? 
How much happiness do you eat? 
You decide it is yourself who eats happiness.
