Topp Dogg's P-Goon and BULLDOK's Say, who are real, biological siblings, met up backstage at a music show for the first time!

It must be a special day for the siblings, since Topp Dogg recently made a comeback with their 1st studio album 'First Street', while BULLDOK recently debuted with "Why Not".
P-Goon, whose real name is Park Se Hyuk, is the older one, while Say, whose real name is Park Sae Hee, is younger by 2 years. Best of luck to both siblings with their promotions!
