"With TOP".
The video features an Alessandro Mendini chair so both the picture and the video might have been taken at TOP's house.
Both Song Kyung-Il and TOP are featured in the video (screenshot via @BigBangBrazil):
Song Kyung-Il is from a Korean band called "History". He and TOP alongside with G-Dragon, XIN, Daniel Lee, Soohyuk and others are part of a group of friends named Nuthang ??.
The music in the background is Kanye West's "All Day". (additional information via bigbangbrazil)
