I'm not sure if this is the one you're looking for, but it's the song we sang when we had a candle pass at our chapter. Kappa really doesn't have a sweetheart song.
I found my man
He's my Kappa man
He's my sweetheart forever more
I'll leave him never
I'll follow wherever he goes
With eyes so blue
And heart ever true
He gave me his pin to wear
The years may pass
Our love will ever last
For he will always be there
