    Alphys turned to Mettaton. “I, um.. need a.. a moment to think about this. I’ll see you later.”

    “Wait, Alphys!” Mettaton tried to reach out to her, but she was already walking toward the basement elevator. “I'm here if you need to- ..talk," She probably wasn’t listening anymore.

     

    And with the way she said it, Mettaton wasn’t sure he would be seeing her ‘later’.

    “good,” he muttered around a mouthful of food.

    “Wow, rude. I have no idea why we’re friends.” You sighed, eyeing the glittery burrito.

    “because you like to mooch off of me,” Papyrus snorted. He finished it off, cracking a grin when you whined in distress. “besides, y’know i only eat this because m’lord made it. he can always tell when i give it away. i’ll get ya something from a food truck later.”

    You nearly cried. “Thank you! I swear, I’ll pay you back when I’m a millionaire.”

    “so, never?”

    “I’ll try.”

    Papyrus shook his head with a grin, reaching out to pat your head. “guess that’s better than nothing.”

    You beamed, soaking up the affection. Papyrus always had your back.

    But… you were still so hungry. You worried that soon, food trucks wouldn’t be enough. Nothing would.
