See Shinwoo skulking about like some sort of thief waiting to pounce on an unsuspecting passerby. He's not really planning on stealing anything, he's just keeping his eyes peeled for those damn bots. The number of times he's had to kiss someone whose name he didn't even know is more than he'd like to admit.
So there he creeps, tiptoeing sideways and edging backwards. He might be watching for bots like a hawk, but he's not doing as well when it comes to noticing living, breathing people nearby him.
