W. D. Gaster x Reader

Eavesdropping

(Fluff)

I didn't really mean to eavesdrop. It just happened, it was part of the job. I work with my boyfriend, Dr. Gaster in the Lab, but in completely different departments. See, he was an actual scientist, while I monitored security cameras all day. But I mostly just watched/stalked my boyfriend. Though he didn't know that. He thought I spent my time meticulously scanning the security monitors for suspicious activity. But literally five people worked there including me, and the front door was always unlocked. The only activity I monitored was making sure Alphys was doing her job and not watching anime, making sure nobody stole someone else's lunch in the break room, looking at the people who enter and exit, but mostly watching Gaster. I also have audio on the monitors so as I said, eavesdropping is a given.

I watched Gaster and Alphys talk but I didn't listen in until I heard, "She's unlike any girl I've ever been with! I swear it's like magic!" I raised an eyebrow and turned towards the monitor. "I thought humans didn't have magic." Alphys joked before Gaster continued "Yea she's a human and she's different but, she doesn't act like it. It doesn't feel like I'm dating another species, it just feels like I'm in the best relationship ever! And I don't feel like I'm Royal Scientist, Dr. W. D. Gaster when I'm around her! I'm just Gaster." Alphys watched, almost in awe as Gaster blushed a lavender color and continued to talk about me. "She doesn't expect expensive gifts. Even though I have money, she doesn't expect a lavish lifestyle and expensive things like a lot of other girls have. But when I do get her something expensive she acts so grateful and happy and I get a shower of kisses for it!" He blushed darker as he continued, "She'd probably still be happy if I gave her some crappy drawing or something I doodled."

My eyes widened some, I didn't know he felt this way. I couldn't help but to smile. I felt like I must be an amazing girlfriend. "Oh god, I know I probably sound like a complete dork right now but, I'm just so happy when I'm with her. And the thing is, I am a dork! I'm a dork and a nerd and a geek and she just embraces that! She calls me her dork, her geek, her nerd! And she supports my nerdy interests and hobbies. She thinks it's adorable when I get excited over an experiment and she listens when I tell her about my work or even a stupid anime. She's always happy with me when an experiment goes well and she'll be proud of me, even if she doesn't understand what I did. And it makes me feel like I did something great!" I watched his smile widen as he talked and bragged about our relationship. Alphys smiled and continued to listen. "And we never fight! The only arguments we've had are things like who gets the last NiceCream, or even over proper grammar, haha!" It's true, we never fight. "I always correct her grammar and humans slang. But, she knows I'm only joking. I remember just a few days ago, we had this stilly argument over a shopping cart, or buggy, or trolley, or whatever you call it. The point is, her and I don't call it the same thing so we were just having this little argument over it but it wasn't a real argument. She got so flustered over it, it was adorable."

I was beaming and Gaster was blushing darker and grinning as he spoke. He was so passionate as he spoke about our relationship. It was as if he was so happy to talk about it, and as if it was the most amazing thing ever to him. I loved how I made him feel. "She's just so different in a good way, and she makes me happy and she's such a good person. I really do love her. In fact, I think that I want to be with her for the rest of my life." My eyes widened and I watched intently as he spoke. He began to speak in a serious manner. He bit his lip some, "It's gotten to a point where I honestly can't imagine my life without her. It's like, without her there is no me. I wouldn't know who I was anymore if she wasn't by my side. It's like I'm only me when I have her. It's strange, like she's a part of me now."

I saw him blush darkly and smile as if he was having a good memory. "I remember the first time we met, Mettaton introduced us. I've never told anyone this, but ever since I first met her, I wanted to be with her. As if I knew she was the one." He spoke a bit softer. "Every interaction made my heart swell, and then broke it because I thought it didn't mean anything to her. Every glance made me feel so happy, and then made me feel like an idiot for thinking I had a chance. Everything meant the world to me and then shattered me and broke me because I couldn't have her." He took a deep breath and teared up some, getting a bit emotional. I didn't know our relationship meant so much to him. I didn't know I meant so much to him.

"I love her more than I thought possible to love anything, from the moment I met her. I fell so hard and so fast and for the longest time I had no idea how to handle those emotions. Countless sleepless nights, dreams about her, daydreaming and consequently walking into walls or messing up my work. I never could get her out of my head, I still can't. I've felt more emotions because of her than I thought existed, before she was even mine. I don't really think I even love her anymore, because I think I've reached something beyond even true love." Tears fell down both Gaster face and mine. "What I do know it that I'm in her hands, no matter what I'll never be able to leave her, my heart has been hers for years, she is my entire world and without her I don't even exist. I'm not me when I'm without her, because there is no me without her, without her I'm nothing at all. I now know that I defiantly don't love her, what I feel is too far beyond that. I live for her."

I leaned back in my seat. I had no idea he felt so strongly, so passionately. I'll tell him that I heard everything later. For now I'll let him think it's just between him and Alphys. I wiped my tears as my phone lit up with a notification from the Undernet. I furrowed my eyebrows as I saw Alphys posted a video called, 'OMG DR. GASTER IS IN LUV'. I opened the Undernet and realized that Alphys had recorded and posted Gaster's speech. It was filled with comments like, 'AW! FATHER MUST REALLY LOVE THE HUMAN! GOOD THING I FAILED TO CAPTURE HER!' '*ew, emotions' and "HOLY SHIT! I didn't even know Gaster could cry! Nerd!' Obviously from Papyrus, sans, and Undyne. Then one from Gaster, in wingdings, saying 'Alphys, I cannot believe you were recording that! What if (Y/N) sees!' Alphys replied almost immediately, 'That's the point.'

I smiled, maybe eavesdropping isn't so bad.
