32-Year-old Lin Ruohan met 23-year-old Cui Muyi. When they first met, coffee was poured on her and she was teased like a "little aunt". She was so angry that she blocked him for the 108th time. But this pair of incompatible siblings actually became the bettors of Heaven's "Red Line Experiment" - Yue Lao bet that they would not last three months, Hong Luan Xingjun firmly believed that true love could break the age gap, and all the immortals made crazy bets to watch. Workplace confrontations, blind date dramas, tug-of-war over design drafts... Every blackout sets off an alarm in the heavens, and every unexpected intersection makes the red line quietly tremble. When the 9-year age difference meets the magician, can this explosive sister-brother relationship be reversed within the three-month deadline?
Purpose: To explore the power of true love in age-gap love, to break external prejudices and inherent perceptions, to show that love can transcend age, break through external interference, and pursue the true heart through wonderful encounters and self-growth.
