YoonA has surpassed another landmark on Instagram!

Back in October of 2015, YoonA set a record as the fastest female idol to gain her first million, and now she's already at 5 million! YoonA had hit 4 million followers back in August, so she's gained 1 million followers in just 3 months.

If you are not one of the 5 million yet, then you can start following @yoona_lim.
