Shootout at The Glorious Hotel! Three rival gangs converge, draw guns and blow out pretty much everything in the room (mirrors & windows) except each other. Afterwards, they all decide to dance, probably because of the summer breeze now blowing through the hotel ("The summer fragrance makes me dance")
Notes:
The Professionals are comprised of assassin Jaeyoon and businessman Rowoon, who seems to recognize - but might not be working with - motorcyclist Hwiyoung. They meet at the hotel and enter together
The Loud Shirt Gang are comprised of Taeyang, Dawon, Youngbin and Chani. They also enter the hotel together and immediately start stirring up trouble
The Gamblers are comprised of Inseong and Zuho. They're the first ones to mingle with the rival gangs and the first to pull surreptitious weapons on them
The Lone Wolf Hwiyoung enters last, hiding his gun in a delivery of flowers. He's the catalyst for this entire showdown, but he doesn't seem to be interested in shooting at people.
MVP: Rowoon for looking like a million bucks and dancing like a dream
