Oh Yeon Seo went topless into the water for her sensual 'L'Officiel Hommes' photoshoot!

She was in such a bad condition on the day of the photoshoot that she even had to get the Ringer's solution, but despite this, she stayed bright throughout the entire photoshoot. Even though she had a harder photoshoot than normal because of the water, she didn't let it show at all.

She's currently filming MBC's new drama 'Medical Top Team', which will start airing on October 2nd.
