IU hadn’t tweeted since December 23 of 2014, which is always a great idea.

However, she came out of a self-imposed Twitter exile to respond to singer Corinne Bailey Rae, who IU loves and fangirls over.
Cute.
This should come as no surprise, though, as back in 2013, IU also flipped out over Corinne Bailey Rae, and the tweets actually show the progression of her English.
