SECRET's Hyosung is back again with a set of photos for the Yes spring underwear collection.

After showing her love for fans on Valentine's Day with a lovely pictorial, Hyosung has another treat for White Day, which is coming up next month. As the latest endorsement model for Yes, Hyosung is proving that she's still the reigning "bagel girl" among idols. Her knockout combination of sexy and cute doesn't hurt either.

A rep from Yes revealed, "For this pictorial, we teamed up with Hyosung to cheerfully express Yes' lovely brand image. This season's apparel that Hyosung is wearing features a design that is perfect for spring with an excellent fit and seamless quality, so we anticipate a hot response."
