‘Ayiao's Exclusive Treasure Box’ #TheLongestPromiseBehindTheScenes# New materials from the Joyful Version of Jiuyishan are here! Shi Ying @X玖少年团肖战DAYTOY and Da Siming @韩栋 exaggerated performances during the shoot, always able to follow each other's cues. Truly deserving of the title 'Drama Master and Apprentice.' #TheLongestPromise#
