Ning Yuan, a freshman, unexpectedly binds himself to a Persona System. By establishing a persona in front of others, he can earn Persona Points and exchange them for skills. To become stronger, he begins playing the roles of a diligent top student, a fitness enthusiast, a basketball expert, and a warm-hearted junior on campus, maintaining his personas while getting caught up in countless hilarious and absurd situations. But he doesn't simply pretend to be someone who loves studying; after establishing that persona, he really spends his time in the library. When he adopts the persona of a fitness enthusiast, he genuinely keeps running. And when he presents himself as a warm-hearted guy, he really does bring umbrellas and ginger tea to his classmates on rainy days. As he continues 'acting,' he unknowingly begins to truly help others and gains friendships along the way.
