Mizuno stated on the 6th, "As a singer with both individuality and skill, Gary, who shows a healthy and sporty image through the SBS variety show 'Running Man' and also normally enjoys exercising, fits well with the brand image so he was chosen as the model."

"As an exercise maniac, he perfectly took on difficult moves and did his best for the advertisement, impressing us with his professionalism."

If you thought Gary was only sexy when he asked you to 'shower later', guess again because he showed that he's more than his cute goofball image on 'Running Man' with his charisma and muscles.
