You and Sanemi had been friends for a long time, until you noticed something different in his behavior. He became more protective and more controlling, but you tried not to think about it too much. While Sanemi only thought about his love for you, he couldn't live without you, so he thought about the only thing he could. You woke up with a chain on your ankle that is connected by the bed. You look around before you hear Sanemi "Ah, you're awake, my little sun."
