Dokusenyoku Tsuyome na Shachou no Dekiai ga Tomarimasen!

Kiyo works in product development at a chocolate manufacturer; she's what they call a "science type" with her white lab coat and glasses, plus her lack of romantic prospects. "I've spent my whole life focused on research, but now I want to give 'love' a try." -- Her mind made up, Kiyo registers with a matchmaking service, but the dates just keep going down in flames... Then one day, she's met with a shocking invitation from the young and handsome president of her company, Mr. Sendo: "Would you like to go out with me? I need you." Kiyo has zero experience with romance, so this well-mannered and gallant man gazing sweetly at her as he calls her beautiful is enough to leave her reeling...! Her heart is still pounding on the day of their date, and then Mr. Sendo suddenly reveals his red-blooded, manly side and proclaims, "I'll shatter that logic of yours with my passion"...?!
