I Just Want to Make Money, but the Sickly Lady Doesn't Want To

(Female hero + non-sexual transformation + normal male protagonist + mature big sister + Shura field + chasing husband) When I woke up, the world's concepts of men and women were reversed. Chen Xiao found that his appearance, which could be called a succubus, was simply T0 in version T0. Chen Xiao, who was trying to make money because of her tuition fees, was tricked by her imperial sister Long Aotian into becoming her housekeeper. However, when she found that the originally aloof look in her eyes gradually changed, Chen Xiao said that she was not a delicate boy. The unrepentant mature elder sister took advantage of Chen Xiao's ignorance of so-called male virtue and went crazy to eat his tofu??? Are you still blackmailing yourself with your salary? Can this be tolerated? Just when Chen Xiao was about to escape, he discovered that the cold and cold sister Yu who originally held Long Aotian's script had awakened the yandere attribute!? The most important thing is that Chen Xiao who was caught was told: There is more than one yandere sister who covets him like this~
