It was Shancai's parents who were worried that she was unhappy and found Daomingfeng, so that Venus' smile (fake crown) was stolen. So Shancai and Domyoji Tsukasa, afraid of being discovered by Daomingfeng, ran to the United States to look for them. In America, they found a habitual thief and thought it was him, but it wasn't. On the contrary, with his help, they intend to win money in the casino (Alaska's) (treasure hunting also costs money) and lose everything. At this time, F4 members appeared. In order to bid for Venus Smile, the whole class took out 600 billion yen, and Domyoji Tsukasa was very moved. In fact, the class knows the truth. Everything seemed to be going well, but an accident happened. Cunningham discovered the secret of class and told Domyoji Tsukasa that Si didn't believe it. He was very angry. He quarreled with Cunningham. Since then, a series of things have happened to test them. They were also left on a desert island, happy and unhappy. Finally, mutual trust proved that they were meant to be. The truth paid off, and they got married and got pregnant with everyone's blessing (such as witnesses and funny clothes)
