"If you feel happy, you'll be busy, if you feel tired, you'll let yourself go" is the lyrics of the song, what is the title of the song?

Not so simpleNot so simple

Can find a companion to talk to

Particularly after seeing so many betrayal

Always upset only tough

Who murdered my romance

Not so simple

Can go to the love of the other all don't look at it

Become practical maybe good maybe bad half

Not so simple

Can go to the love of other all don't look at

Become practical maybe good maybe bad half

Cozy up on the couch

It's not that easy to love each other

Everyone has their temperament

After the age of dreaming

It's better to have peace of mind than to have a big bang

Happiness isn't that easy

This is what makes it especially mesmerizing

An age when you don't know much

It's the age when you don't know anything. p>

Once the most heart-rending

So the happiest ever

Miss the saddest

But the most moving memories
