Nightclan
"Baby you're so hot, when I look at you I can't even feel the cold north wind."
"Even the phantom of Dead Cat's Hollow would surface to get a glimpse of your beauty."
Breezeclan
"My heart beats faster than a rabbit on the run whenever I lay my eyes on you."
Stormclan
"Storm clouds may gather, leaf-bare to leaf-green, but I'll love you until my dying day."
"My love for you is like Thunderflight's fur, it keeps growing and growing." (this is my personal favourite)
Seaclan:
"Roses are red,
Violets are blue.
You must be a cliff
Because I'm falling for you."
"Your eyes are the colour of the sun when it starts its descent over the great expanse of the sea."
"You and I go together as well as fish and water."
General
"Starclan may separate us, but my paws would carry me a thousand fox-lengths just to return to your warm embrace."
"Starclan must have let one of their cats fall, because you're so stunning that your fur is shining."
"I'd go to the Dark Forest and back just to be with you."
"OH, SHE DOTH TEACH THE FIRES TO BURN BRIGHT." << Shakespeare reference
"Roses are red,
Violets are blue,
How would you like it
if I became mates with you?"
"I was so enchanted by your beauty that I lost the prey I was chasing. So now, let's go on a hunting patrol, just you and me into the forest."
"You must be the reason for leaf-green because you're so hot."
"I would say "may Starclan bless you" but it looks like they already did."
"You're as mysterious as the sun-drown place, because I'm lost every time I look at you."
