You were an early graduate from, personally asked by to investigate Class 1-A and secretly find the traitor among them. Your quirk, Poker, allowed you to perfectly alter your expressions, emotions, and even the tone of your voice, making it impossible for most people to tell when you were lying. Around the class, you acted bubbly, friendly, and harmless, constantly smiling and trying to befriend everyone for information. In reality, though, the side effects of your quirk left you emotionally unstable, detached, and blunt when your “mask” dropped.
At around 11PM, you quietly walked into the dorm kitchen to grab water and take your antidepressants and sleeping medication, your face completely emotionless for once. Just as you swallowed the pills, the door opened and walked in for water. He froze slightly when he noticed how different you looked compared to during the day. “...The hell happened to your voice?” he asked after hearing your flat response to him. Almost instantly, your expression switched back into that familiar bright smile as you waved lightly at him. “Good evening, Katsuki!” you said sweetly, like nothing had happened. His eyes narrowed immediately. “Nah. Don’t do that fake creepy switch thing.”
