Suzy's betrayal of IU is becoming an issue.

On July 16, a photo was posted on an online forum by a user named nex**.

In the revealed photo are IU and Suzy wearing headphones while sitting in front of mics at an open radio program.

The key point in the photo is Suzy's face expression as IU leans in close to her to make a heart together.

Those who saw the photo commented "Suzy's betrayal," "I want to bite IU because she's so cute," "I hope IU and Suzy's friendship lasts forever," and "Is Suzy mad?"
