His favorite girl should be Joy, and he really wants to marry Joy. But because Tigress framed him, he had to marry Tigress.
Tigress is also an aggressive and ugly person. For Xiangzi, marrying her is a very painful thing.
Their marriage was originally planned by Tigress, and Xiangzi certainly didn't want to marry Tigress.
Coupled with Tigress, she is aggressive and fierce. Xiangzi likes that petite and lovely joy.
Besides, Tigress's father drives a car, which means that after he marries her, he is equivalent to a son-in-law. However, for Tigress's father, it is equivalent to having one more person to eat at home. He didn't treat Xiangzi as a son-in-law.
