In the clip, Sungjae is excited to find Chorong in front of him in a white dress holding a gift. However, the unexpected happens when Chorong suddenly flips him to the floor. 

As previously mentioned, '9th Boy', written by 'The Romantic's PD Yoo Hak Chan and 'We Got Married 4' writer Park Yoo Mi, revolves around men whose age end in the number 9 (a superstition that you reach your climax at the ninth try, etc.). A Pink's Chorong and BTOB's Sungjae will act out 19 year olds Soo Ah and Kang Min Goo.

'9th Boy' is set to premiere on August 29 following the finale of 'Marriage, Not Dating'.
