Summary
Tenna sat on his heels, balling fists into his lap. Thank god the backstage shadows worked in his favor. Also worked against him, too, because he couldn’t tell if Mettaton glanced back. To thank him, to ask if he was okay. Maybe offer another smile, just because. In a matter of seconds, Mettaton marched off, flanked by crew members for final preparations. Talkback reached Tenna: sixty seconds until Mettaton went live.
Of course. Almost showtime. No reason to pull his star performer aside and... ugh, do something dumber than whatever bullshit he pulled off. Snarling past a mouthful of static, Tenna rose and excused himself. Needed to make the rounds backstage and ensure everything ran without a hitch. You know, do his damn job in the Dark World. And not fixate on the fresh memories branded in his circuits.
Easier said than done. Fucking hell, it always was.
An unfortunate accident occurs before Mettaton’s debut performance, leaving two possible outcomes once the curtain falls: he’ll leave TV World and Tenna for good or he’ll ask to pick up where they left off. Luck’s never been on his side, but Tenna hopes it’s the latter. He really, really, really does.

Summary
Mettaton had been gifted Tenna a few months ago, and thanks to the Dark World, he is able to hang out and talk with his new CRT friend! The two have been hitting it off with their friendship, but some new feelings have emerged, something more than a friendly bond. Having become familiar with each other more intimately, Mettaton wants to try out something new in bed with Tenna. Just what is it then?

Summary
“Easy there,” he murmured. “No need to rush it. Baby steps. Take it a night at a time.”
Mettaton clutched Tenna’s hand like his life depended on it. The pink in his cheeks deepened in saturation. “What if it takes me forever to get it right?”
“Then I guess I’ll be working forever and a day, huh?”
After acquiring a corporeal body in the Dark World, Mettaton yearns to put his new legs to good use. Quite the tall order, considering he doesn’t know how, but Tenna is more happy to teach him, no matter how long it takes.
Or 5 times Mettaton is swept off his feet and 1 time Tenna is instead.

Summary
“Wait a second,” Tenna said. “Did you—”
“Pay my mechanic friend a visit to implement those upgrades we discussed two months ago?” Mettaton finished his question, nonchalant while examining nails he didn’t have. “Oh yes, I believe I did.”
Okay, he had to bribe Alphys with an overwhelming stockpile of eroge visual novels and six dakimakura covers of questionably proportioned anime women to patch his joystick strap-on, but that was a price he was willing to pay (literally—with a credit card).
For the past year, the masses have speculated if romance is blooming between the rising star and the veteran TV host. Great question. Honestly, Mettaton has been wondering the same thing—and he’s the one literally railing the guy two hours before their joint interview.
