The usual reaction to sudden hugs from MK is still largely to instantly shove away and grumble. Maybe one out of twenty he allows the contact to persist.

Mei is like one out of four, training arcs happen, she gets more frequent touch rights.

So it may be telling that Red Son hasn't immediately shoved MK away at the tight hug, just stumbling back to get his balance again.

"Will you-" He huffs. "Do you have to be so dramatic?" He says like he hadn't partially ignited at the sight of MK and immediately rushed over and the only reason he didn't TELEPORT over is because there were too many people around and that is a tight needle to thread.
