Hyosung revealed that she had made sure to check over how much exposure was required for her contract with lingerie company 'Yes' before she signed it.

She was the first idol ever to signup for a lingerie photoshoot and a question was posed to her recently on MBC Every1's 'Weekly Idol'. The MC's asked her, "You were the first idol to endorse for lingerie. How'd you feel about it?". She answered, "To be honest, I was a bit burdened. Before my CF shooting, I made sure to check the level of exposure and also made sure to check the financial amount multiple times."

The toned down look has worked out well for 'Yes' as the company experienced an increase of sales ranging from 40%-50% compared to the previous year.
