Looking for a historical yaoi manga

Im looking for this historical yaoi manga I read a while back. i forgot its name. It was about two people who "hated" each other but they were actually in love.....they had a scenr where when they were having sex, a woman saw them and the mangaka joked that that was how the first fujoshi was born.......then there was another scene where the two were kissing under a wisteria tree after the uke searched for the seme and he got scared.....does anyone know the manga? Id really be grateful if u cud tell me the name of the manga
