Shen Mingzhu, the daughter of the richest man, was forced into a marriage to the cold-faced prince Xiao Yan. On the night of her wedding, she accidentally set up a truth bubble system. Whenever the prince said something he didn't mean, a transparent text bubble would appear above his head, and everyone in the room could see his true thoughts. In front of others, Xiao Yan coldly declared that he would only marry her for the sake of the treasury and to secure his position, but in his heart, he bluntly wrote, "Her waist is so thin, I want to hug her so much." When they first met, they were shocked by everyone.
The Queen Mother suspected that Shen Mingzhu was born as a merchant and secretly supported the princess of a neighboring country. She repeatedly set up situations to create difficulties. She also secretly drugged and sent assassins to harm her. She just wanted to replace the Crown Princess. The concubine Shen Mingyao admires the prince and constantly spreads rumors and frames in an attempt to replace her. Veteran officials in the court also complained one after another, questioning Shen Mingzhu's status as being unworthy of entering the central palace.
At every banquet, morning court, and palace banquet, the prince spoke harshly and bubbles filled the screen with bubbles above his head. All civil and military officials and everyone in the harem ate melon. There were endless scenes of famous social events. Xiao Yan was shocked at first and tried desperately to cover up, but later accepted his feelings calmly and took the initiative to protect his wife. He teamed up with Shen Mingzhu to tear apart the conspiracy of the Queen Mother and the concubine, and uncovered all the evidence of poisoning in the harem and collusion with foreign enemies in the court.
After experiencing turmoil in the palace and war on the border, the two went in both directions. Xiao Yan put aside the pretense of being an emperor and openly revealed his full heart's preference. Shen Mingzhu no longer relied on bubbles to identify his true feelings and understood the tenderness hidden under his indifference. In the end, Xiao Yan successfully ascended the throne and named Shen Mingzhu as his queen. For the rest of their lives, they would not need any bubbles to prove it, they would treat each other honestly, and they would enjoy the prosperity and the warmth that accompanies them every year.
