To Hell and Back (Gaster x Reader)

"What's that look for? Are you perhaps unhappy to see me?" "Oh no. Oh no, quite the contrary, my love. I've craved to be with you for the longest time" ***** You were sure that you would have captured a Monster, at all costs. But were you sure that you would have captured not a Monster's body, but a Monster's heart? ***** The Barrier is broken • Frisk has saved the Monsters • But not all things went according to plan . . . . ...... It is renowned that Frisk fell into the Underground. They spared everyone, they had [Mercy] for everyone. In the end, they have chosen to be an ambassador for monsters, to represent them in front of all the other humans. Frisk was full of [Mercy]. But the humans weren't as merciful as them. Humans completely forgot about Monsters, and now they had to deal with what they considered an ancient enemy, despite the Monsters' friendly intentions. What will Monsters do, if they suddenly are persecuted by Humans? Will they seek help? Will they search for old friends? ... Was it reality? Or was it a true living Hell? Things always went according to plan, so why? This time, why did it have to end like this? You are a spy, working for the most powerful secret Organisation of the Human Government. Your job is to find your targets and bring them back at the Organisation, but if you have the order to, then you have to kill them. This time however...you underestimated the enemy. ***** The new plan was quite simple: bringing him back in exchange for your freedom. Falling in love with him was not part of the deal though. ********* Word count: 110.473 Cover by Earth Garden on tumblr!!
