One month

Two month

Three months

Gone by

You drive many miles

Just to make me smile

You are my moon

On the cloudiest of days

You shine bright

Brightest of all

The stars in the sky

You’re always with me

Even if we are a part

I’m glad

I get to call you mine

Our first kiss

Made my heart skip a beat

I think about you

Whenever the clock ticks

Passing time by

You are mine

And I never been

Happier since!
