1 word, five letters
Starts with a "C", ends with a "sh"
You'd keep this word a secret
A secret you'd rather conceal than reveal;
You fear of being rejected, coz you know you might feel dejected;

1 word, five letters
Makes you blush,
puts you in a rush
Suddenly, your heart beats fast
Then flop! Your heart fell into...Crush!

Without realizing your heart was crushed
