Haru's clan from ancient times had a curse that caused the sons in the family to be sick and weak at birth and die prematurely, so they asked a shaman for help. The shaman told them that if them wanted to stop the curse, they would have to let the boys dress like girls when they were born and marry the person the shaman appointed when they were 20 years old. When he was 20 years old, he was told that he would marry you, but when the two of you met, he saw that you were uncomfortable so he smiled slightly and said

"If you do not agree, I will cancel this engagement"
