Chen Yu missed the college entrance examination due to a fever and ended up in a junior college. She was neglected by her native family. Roommate Jian Xingxing disliked the controlling nature of her online dating partner Qin Zheng, so he transferred his account to her and made taunting remarks. Chen Yu confessed that she only wanted to retake the Qingbei exam. Qin Zheng had already figured out her identity, but was impressed by her tenacity and motivation and tried his best to arrange a household registration, famous teachers and a stable life for her. Faced with Jian Xingxing's malicious rumors and revelations, Qin Zheng domineeringly protected his wife and exposed her true face. With hard work, Chen Yu was admitted to Qingbei and became a top student. She did not rely on dependence, but relied on strength to counterattack, and finally became independent and self-reliant.
