A gray box

It wasn’t that Luke was unhappy at Irons and Works. After all, that was his home, his family, his safety.

But watching everyone around him fall in love was a bit much when every single relationship he’d tried to maintain fell to pieces. Was he just unlucky, or was there something about him that was just fundamentally unlovable?

What Luke doesn’t expect in answer is an older man with greying hair and eyes that look like they’ve seen into the core of the earth.

What he doesn’t expect is for Tony to introduce everyone to his half-brother.

And what he most definitely doesn’t expect is for that man to zero in on Luke, and decide—whether Luke likes it or not—that he’s the only thing in the shop he actually wants.
