A bulletin post in an online community caused a stir as it showed something nobody expected.

The bulletin post was titled, "Han Ga In and Krystal - They filmed a commercial together 10 years ago?" The post included a video clip of the actual commercial that Han Ga In and Krystal appeared in. It was a beverage commercial.

Han Ga In was a newly debuted actress at the time the commercial was filmed. She looks pure and innocent with her long straight hair that flows freely in the wind. Han Ga In's pointy nose, her trademark, is the same as it was 10 years ago. 

Krystal also looks very innocent as a little girl in the commercial. The commercial proved that Krystal is a natural beauty.

Netizens who saw the photo responded with comments like, "Wow, I didn't know they were connected this way", "They're both so pretty", "Han Ga In looks so innocent", "Krystal is so cute and adorable" and etc.
