Peace through political marriage. Will the marriage last when one has already given her heart away? (A bit of Bellarke at first but trust me, it gets better)

Born in 2020. Frozen in time in 2038. Nuclear Apocalypse in 2052... wait, what? - I wasn't supposed to wake up this early. I had another 15 years left yet. But that didn't matter. What mattered was that I had woken up in an entirely different world from what I expected. There weren't robots or flying cars, no way. Instead, there were these really scary people with scars and face paint, and I had no idea where I was. - Y/F/N woke up 15 years earlier than she was supposed to. Being frozen in time was never on her to-do list, but if it meant supporting her parents in a possible groundbreaking discovery, then she was all for it. However, that was with the expectation of waking up in the future. So, how come when she woke up, it was like she took a step into the past?

『sequel to Frozen In Time』 After defeating Ice Nation and its queen, Y/N and Lexa truly believed that they could finally have their happily ever after. They were wrong. For the second time in this post-apocalyptic world, Y/N is kidnapped by an enemy that she didn't even know she had to fear: The Mountain Men. After losing something irreplaceable of hers, she has to find a way back to her home without starting World War 3. Lexa and the Grounders have to form an alliance with a new set of inhabitants of the earth: The Sky People, in order to get their time-jumper back. But will it be that easy? Or will an unexpected someone make that task even more difficult than it already is? (Gifs used are from google images, so credit to their rightful owners!)
