According to 935 Entertainment, Yeon Jung Hoon had an advertisement shooting on May 1 but they didn’t disclose more details about it. But from the little infos I got from the IG of his stylists, I think Yeon Jung Hoon will be endorsing for a coffee & bingsoo (shaved ice) franchise brand. My guess is ‘Caffé Laterre’ 😉 Below are some pictures of him during the ad photo shoot shared by his agency & stylists :-
Sneak peek at the coffee brand he’ll be endorsing!
