She says she's changed as much as he has in 10 years, except she's not realizing he's just as in love with her now as he was 10 years ago and he has probably changed not as much as she think he has. Makes me think she's much more hung up on Eunhyuk in the back of her mind than she wants to admit. Her tough guy smoking ruse kind of proves it in a meta narrative way that she's bluffing more than she's moved on/changed.
