Haitang has taken care of knives since childhood and indulged them everywhere. However, as an adult, at first, he failed to distinguish between brother and sister, and unilaterally fell in love with his brother TIANYA DUAN. Later, he learned that Tianya had a lover, Yukime, and vowed never to get married. Later, I met Park Xu and got married because of the cure. Haitang quickly cut the gordian knot and finally understood that although it is close to the end of the world, it is just brother and sister. After leaving Japan, I went through a lot of hardships and finally found myself deeply in love with another spy.
