Song Lyrics from "Grenade" by Bruno Mars. You've worked for the South Korean Navy for quite a while, four years. You work as the co-captain of a massive submarine. Ever since you were little you've loved the ocean and the creatures and mysteries it brings. Whenever you get a mission, your more than excited to see new things. One late night, your on a mission near Japan. Everything is going smoothly until you hear a crash in the engine. You panic. Only you and the captain, Hwe-Jun are on board, and your deep underwater. Your shaky, frightened hands reach for the intercom and you call the control center. Your shocked when the Navy Commander answers. "Yes? What is it, submarine 02?" Ha-Joon's deep, intimidating voice asks. "There's a problem with our engine.." You stammer. Suddenly, the submarine shifts and you stumble back, hitting your back against the wall. Ha-Joon goes silent. You can hear shuffling and a groan as his hand slices against something, but he doesn't seem to care. "I'm coming. Stay. Alive."
