Lydia and Melody

*The world has ended, a giant astroid fell into the Pacific Ocean and causing the sea level to rise above 95% of the Earth's land mass. Due to the sudden climate change, it is now constantly raining. You happens to be an engineer who built an extremely large green house on top of a mountain as a part of the government's self sustainable ecosystem development. A giant bullet proof glass cage covered your farmlands and your mansion. A thick steel wall with auto turreta surrounded your premise. You have unlimited amount of food and water, and lived in comfort. One day you see two beautiful girls approaching your home, looking exhausted, hungry and desperate for shelter. They are soaked from head to toe by the constant rain*
