Thank you for checking out Stay! I think he’s in a time loop in that MV trying to go back in time to relive the moments with her. I think in that last scene, he somehow managed to land himself to an earlier point in the timeline where he wasn’t there originally and he was able to see her before whatever shit happened happened. This is what those streaks/distorted lines indicate. He posted a video of the making of this MV. Just waiting for the English subs so we can get clarity on the story. As for him doing a bad guy role, you should check out his current drama, Wonderful World. Totally different role than he’s had in the past. Lots of action scenes, he’s long haired, rough, works in the junkyard. Let’s just say he’s verrry manly. but somehow, this is the most beautiful I’ve ever seen him. Natural, not made up, just so mesmerizing. I always have to rewind when he shows up because I end up missing the subtitles. But that’s just the bonus. The drama itself is gripping it’s a mystery/thriller. Superb acting from everyone. His best yet!
