For the last eight years or so, we've known Mark Tuan as a K-pop star, a member of GOT7, and a quiet but fierce rapper-singer. Through all of that, he's been a happy bundle of joy for his fans, often putting forth the side of himself that's positive and energetic. 

And while that's all still a very real part of who he is, there's a whole other side that rarely makes its way out into the world. Until today.
