夜這いを決意した令嬢ですが間違えてライバル侯爵弟のベッドにもぐりこんでしまいました

Synopsis

Baron's daughter Chloe is at the edge of a cliff due to her family circumstances. In order to overcome the current situation, she visits the Marquis at night! …Or so she thinks, but really she crawls into the bed of Ray, the Marquis' brother. Her former rival who competed with her for the top spot at the Royal Academy said, "You're a virgin, aren't you? In order to make your night crawling a success… Shall I help you?" She decides to accept, but-?! A doting story of an honor student young lady with zero love experience and a nasty high-spec marquis brother!
