Qin Yan and Li Qingya unexpectedly both experience rebirth, returning to their freshman year of college. In their past lives, Qin Yan's vanity led to deep regrets. After being reborn, he casts aside superficiality, relies on the opportunities of the times to start a grounded business, clears up past misunderstandings with each other, upholds the baseline of law and morality, drives his roommates to strive together, supports physical industries, and assists youth entrepreneurship. Keeping a grand sense of national duty in their hearts, guarding their original intentions and warmth, they grow towards the sun amidst the tides of the era, walking out a brand-new, upright, and magnanimous life.
