Jackson's left to film for long periods of time before. That didn't mean that they got any easier for Mark to handle. But this time, the show is different from anything else he's done. Real Men isn't something he can just joke his way through. With just hours left, Jackson starts to panic that maybe he won't be good enough and Mark has to reassure him that everything is going to be alright. Originally posted on 

No words in any language could ever accurately describe how Mark felt about Jackson, especially during moments like this. The younger never failed to surprise him in the best ways possible. He’d always shown an interest in kids before, always wanting to make them laugh and smil

Who knew being away for just a few days could be so torturous? Mark couldn't stop thinking about the boy they had to leave behind this time. He texted as often as he could, checking to make sure Jackson was resting and taking his medicine and eating something, even if he didn't feel like it. But when their plane finally landed back in Seoul, Mark felt the sudden urge to call the other. He just wanted to hear Jackson's voice again.
