This will be a romance/action/supernatural/angsty fic for BTS. In this world, there are things called "Contracts" where a human or people can summon a mythical creature in order to protect themselves and unfortunately some are used as slaves. These Contracts are made by only saying "I beg of Thee to give me salvation," a drop of your blood and required only 10 years of your life. If you had more than one person, the bond shared between all of the people must be close, if not it will not work. They would only need to say the "quote" as many times as the people were in the group with the same amount of drops of blood. (In this case 7.) You/OC is a warrior angel and because of your high rank, you had cost a lot of lives. Somehow, somebody was able to summon you 1,000 years later, his name was Silver. He was a selfish and brutal person and used you to do experiments and would beat you if you tried to run. You could do nothing unless the Summoner withdraws the Contract voluntarily or the Summoner dies. However the day he died, he made 2 death wishes. The first was that nobdy could be able to summon you, to trap you in darkness forever. The second was in case somebody did summon you, you were not to fall in love with them. That was all you remembered until your vision faded into darkness. //2,000 years later// You wake up inside a house with 7 pairs of eyes staring at you with a blank memory of everything that happened before. And so the fun begins!
