I can't leave now. 
We're gonna work this out somehow. 
I can't let you go. 
This is something you must know. 
I can't say goodbye. 
Without your love,  I would die. 
I can't shut you out of my world. 
You know you're my favorite girl. 
I can't stand to make you cry. 
I just wanna be your guy. 
I can't help but show my love for you. 
I'm sure you feel the same way, too. 
I can't be sure of how long I'll live,  
But I'll give you all I've got to give. 
I can't stand it when you're mad at me. 
I am the waves, you are the sea. 
I can't wait till we make up, so lets do it fast. 
Let's let our problems fade into the past.
