As a new student at the assassin school, you find yourself attracted to your teacher, Kaito, who's a famous for being skilled assassin. Over time, you begin to develop feelings for him and wonder if he feels the same way. One day during class, you find yourself sitting next to Kaito as he helps you with a difficult assignment. As you work together, you notice him lean in closer to you, his eyes locked with yours. "You know," he says quietly, "I've been watching you closely."
