Darkness' Eternal Bride (Gaster x Reader)

Chapter 20

A flashing blue and yellow eye

"Try this" Gaster said as he helped you perfectioning the time machine in your lab, handing you instruments.

Two whole months had passed since you and Gaster became a thing, and ever since then he helped you when he could with your project, something you really appreciated.

His subordinates now had gotten used to his more and more absent presence at his lab: when Gaster wasn't there, they knew that he was with you. But at least, they were happy for both of you.

Overall everyone was happy for you: Toriel had even thrown a party at her house to celebrate the new couple, and you can actually say you had fun.

Well, except for one person.

Jayden often texted you some days to invite you out, and sometimes he even said things like "I love you". Everytime he would text you messages like these, you would show these to Gaster, he would glance at them slightly disgusted and he would erase the distance between you two by kissing you, and passionately, reminding that you were his girlfriend.

And now there you were, adjusting the time machine, with him by your side, lending you tools to prepare codes and arrange mechanisms.

However, the more you worked, the more you grew doubtful about one thing, and your face clearly didn't hide your inner thoughts, as Gaster immediately noticed that something was going on.

"Y/N, are you okay?"

You blocked yourself when you heard his words, partly softened by his question: it meant he cared, and you found yourself safe in his tenderness.

"Yeah, I'm okay. It's just...I'm having doubts about this time machine" you said in the end.

"What kind of doubts? You don't want to construct it anymore?"

"No...well, I don't really know at this point. I mean, do I really want to bring back Lauren, or am I just too much dedicated to this project to abandon it now? How would my life be if I didn't kill her? Would we still be best friends? Am I feeling obliged by the sense of guilt I felt before? I don't know what I feel" you said before you could hiss in pain as you got yourself hurt with an instrument, and got yourself a cut on your hand.

"Damn it" you said in pain.

"Wait, come here, there's medical equipment over there" he said, grabbing your other hand and conducting you to a table nearby, where there was a small white suitcase with a red cross in the center.

He made you sit down on the table and he opened the suitcase, picking up disinfectant and bandaids.

"Here, let me have a look" he said, professional as ever.

You showed your hand and he examined it, carefully touching the area where you were not hurt to understand how deep was your cut.

"You're lucky, you could have gotten a worse cut than this" he said as he picked a piece of medical cotton and moistened it with disinfectant, putting it right after on your cut gently.

You hissed in pain again, catching his worried glance. How cute, he was afraid for you. You smiled for him, to reassure him that everything was okay, and he immediately got relieved after seeing your smile.

"Thank you dear" you said as he put the bandaid on your hand and gently rubbed it right after.

He smiled and looked at you tenderly as he rubbed your hand delicately.

"So, about what we were talking about..." he started talking as he looked at your hands and continued caressing them.

You slightly gasped after remembering what you were talking about before you got hurt: bringing back Lauren.
