THIS REALLY ISN'T BAEKHYUN! 

His name is Em. He's Thai and he's part of a cover group called Millenium Boy (they cover EXO dances).

Here are more pictures of him.

Here's his facebook page: https://www.facebook.com/EmMilleniumBoyFC

He actually doesn't look like Baekhyun in other angles. It's just those pictures.

I feel like he can be an ulzzang, LOL.
