So a cyhydedd fer is a Welsh form of poetry which is made of couplets of 8 syllables.

Four months ago you held my hand,
We stood with other cheering fans.

Your face was pure and soft that night,
Outlined by artificial light.

You leaned your head into my chest,
And kissed me softly as you left.

I guess for you it was not real,
You'd never know just how I feel.

Your mask of beauty led me on,
But all for naught, for now you're gone.
