Resilient Heart: Light in the Chaos

This is not the first time. In this chaos, everyone is looking for a way out. There is no collision between elements; no one cares about the other. They just want to see you fall and then ask a fake question: "Do you need help?"
This is total darkness. Suddenly, you find yourself in this world, alone, hearing the sound you ignored during this period, the sound of your heart. Your heartbeats can be the only reason to move forward, brighten your surroundings, and save yourself from the chaos around you. Find the reason that makes your heart beat: you, him, her, or it.
