The selca is from August of 2015. Sulli is captured flashing a big smile next to Dynamic Duo's Choiza, her boyfriend at the time. Then to her left is her current boyfriend Kim Min Jun. Crush, Gaeko, and more artists under Amoeba Culture are also spotted making goofy faces in the photo.
This selca also draws attention to Choiza and Kim Min Jun's relationship. The two were reportedly friends for almost 10 years.
Based on the various 'evidence' including Choiza's past suspicious Instagram post, some netizens are convinced that Sulli must have cheated on Choiza for Kim Min Jun.
