SNSD’s YoonA and Son Eun Seo have become a hot topic thanks to the recently surfaced pre-debut photos that showed off the girls’ natural beauty.

On February 6th, the above behind-the-scenes photos from YoonA and Son Eun Seo’s Clean & Clear CF were uploaded onto an online community board with the caption, “YoonA before her debut at a CF shoot with Son Eun Seo”.

Netizens praised, “The two are perfect for being commercial models” and “Spring girl aura~ I get happy just by looking at it.”

Meanwhile, YoonA will be making her return to the small screen through upcoming drama, ‘Love Rain‘, while Son In Seo will be partnering up with Super Junior‘s Donghae for an upcoming episode of ‘We Got Married‘.
