"Alphy..."

Alphys didn't look away from the screen. "Hm?"

Undyne stood behind her, her arms around Alphys's neck loosely, pressing close to be cheek-to-cheek. "You busy?" she wondered, her voice soft, smiling.

Alphys paused, then focused on the screen for a moment, her claws flying over the keyboard. "Huh?" she then added, realising that Undyne had said something to her.

Undyne paused, too, her smile flickering. She took a slow breath, before she asked again, "Are you busy?" And again, she pressed her cheek against Alphys's, only this time she coupled it with a kiss.

"Augh, no!" Alphys snapped, putting a hand to her microphone and snapping out, "Reverse, reverse!" She then sighed in exasperation, her hands pushing her glasses onto her forehead to rub her eyes. "Sorry, Undyne. What?"

Undyne was standing a foot behind her now, startled back by Alphys's outburst, her arms crossed over her chest and her face now a scowl. Alphys, however, didn't see it, as suddenly her attention was caught again, and she snarled, "I said reverse! You chose to ignore me!" And again, she was glued to the screen, her claws going back to the keyboard and flying over it faster than Undyne could follow.

With a sigh, Undyne turned and walked away, going to the bedroom briefly to change into work-out clothes. Once done, she stomped her way to the basement, slamming the door behind her.

Alphys heard it and blinked. "What's that about?" she wondered. She was about to get up to investigate when someone suddenly greeted her, and she sat back down and returned it with a smile, utterly oblivious to what had just happened - and what she just missed out on.
