The Equation of Happiness

What would my childhood self think of the person I've become today?
Is the version of adulthood I once dreamed of...here now?

As we navigate the complexities of the modern world,
we often lose sight of what true happiness really means.
We hesitate, struggle, and stumble.

And yet--
the formula for happiness has always existed within us.

PRML5`s new single ``Shiawase no Houteishiki (The Formula of Happiness)``
is a message song that speaks to the heart,
urging us to reflect... and move forward.
