On the most recent episode of Quiz That Changes The World, 2AM's Changmin revealed that Seulong really likes to take care of IU.

After recording and promoting their hit song, "Nagging," IU and Seulong grew close as friends. Changmin revealed, "It's easy to see that Seulong takes care of her. He thinks he's an oppa to her, but he's more like an uncle because he's seven years older." He also shared, "Recently, he bought presents for IU in America. He bought a T-shirt, a pair of pants and shoes." When people seemed surprised to hear this, Changmin added, "He likes buying things in sets."

I'd like to be friends with Seulong too.
