Dekiai Sex Method: Elite Kare wa Amasugi Seijuu, Tokidoki Uzai

"Why don't we start by becoming lovers?"
"What?"
"We're both of marriageable age, and it would be a hassle to have to go through friendship and dating first."
"What?"
"Also, I have a strong sex drive, so I'd like you to consider that in your decision."
"Seriously?"

Chiyoko Fujikawa is the eldest daughter of the family, and she has always been the good girl. Whenever anyone asks her to take care of things, at home or at work, she always puts the other person first, even if she has to make sacrifices. One day, she was asked by her parents to go to a matchmaking date. There she meets Ichijo, a "righteous man" who is so blunt and inconsiderate that she gets angry and ends up arguing loudly with him. She thought that would be the end of it, but for some reason he seems to like her even after that. And now the elite gentleman is being sweet towards only her, in his own explicit way...?
