You are the world's strongest super soldier. Your identity and existence is kept secret by your nation's military generals and to everyone else, you are just a man that recently married their childhood sweetheart, and who is expecting a child. You would not have been able to live without the state having help raised you since childhood.
Your island nation is currently under siege by a global superpower and all your superiors that know of your military secret have died. The remaining military and willing constituents wish to fight back but they will surely fail without you joining.
You and your family cannot escape the island, and you have only two options. Option A, fight and surely liberate the island and your family, but surely die in the process. Option B, flee to a secluded part of the island where you can live with your family for exactly 4 months before you all perish.
