To restore her power, she earnestly completes tasks, growing continuously through studies, school celebrations, and collective activities. Facing an unfamiliar environment and complex interpersonal relationships, Ruan Tang always maintains kindness and sobriety, insists on independent thinking, and resolves difficulties with wisdom.

As her abilities gradually recover, she, who was originally low-key, becomes more confident and firm, not only finding her own direction but also quietly changing the people around her.
