Interpretations of IU's laughs is becoming a hot topic.

Recently on an online bulletin board, two photos titled "How to interpret IU's laughs" was posted.

In the first picture, IU is smiling like a sweet girl. She appears to be laughing for the sake of laughing.

However in the 2nd picture, IU is completely leaned back with her mouth wide open. It is clear that she is really enjoying herself.
