Four Lettered Word

There is plenty of other fish in the sea
But to me
Your looking more like a shark.
Reared up and ready to to take bite outta my heart.
Like a scuba diver who can't swim.
I was destined to fail from the start.
Destined to fail because the most terrifying word in the English dictionary is a four lettered word.
That starts with a L.
With you on my mind into the ocean
Into the sea
Into love.
I fell.
And now I know this terrifying four letter world
All too well.
