Yesterday, the group unveiled individual teasers of Mark, and JB followed the day after. Several hours after JB's individual teasers, GOT7 surprised fans with a cut of the 2 members together. The release was not mentioned in the schedule for 'Flight Log: Arrival' but hey! iGOT7s don't mind the extra handsomeness.
The full release is coming on March 13. Watch out for more!
