[Because of Shinwoo's recent suggestion for him to play more games... Today, Setsuna did decide to follow the advice and play more. He's currently by the arcade's entrance as well, controlling one of the game machines.
He really didn't have a game that he prefers, as someone who didn't play much of them, despite being technologically knowledgeable. He was far too occupied with his duties back at home to play around things like these, which is the reason why Shinwoo pushed him to enjoy life more.
... And since he didn't have a game that he prefers (at least, not yet!!), he's playing one of the UFO Catchers. The joystick and the console controls are like a baby version of the devices he deals with back home, so he's playing through with no effort at all.]
