"I don't know when it was, but the you who was smiling isn't you anymore. 
If your heart can no longer give me that kind of love anymore, I will still remember those memories."

Inspired by EXO's Promise. 

Note:
If you have someone you love with all you heart, whether it be your family, friends, or other half, really cherish them, and love them till you can't anymore. Life is so short, and the amount of tieme you get with them, you'll realize how short that really is once they're gone. Just because you were smiling and laughing just yesterday doesn't mean they will be there today. Just because you were having fun with them today doesn't mean they will continue on tomorrow. Just cherish them.
