Who says true and false heiresses must be an arena of competing family assets? The false heiress Su Lanyue waited bitterly for the true heiress Su Qi'an to return home to shoulder the family business, only wanting to peacefully be a slacker; while the true heiress Su Qi'an was single-mindedly intent on lying flat and making music, eager for her younger sister to take over the company. The two sisters secretly acted like overachievers and 'competed' in secret, but both of their entrepreneurial ventures collapsed by lying flat, and only after showing their cards did they realize they were kindred spirits. From harboring individual thoughts to shoulder-to-shoulder chasing dreams, it turns out the best family is never forcing you to be excellent, but accompanying you in lying flat, and also accompanying you in shining.
