Supadari Shachou to Gisou Renai

After her boyfriend unilaterally dumped her, telling her to break up with him because he'd found a new lover, Rika was drinking away her sorrows at her favorite bar. As she continued to drink, she ended up inviting the handsome Kunieda, who happened to be sitting next to her, to spend the night with her, and made a mistake... The next morning, feeling a little awkward, she headed to work, thinking positively that she would only have to meet him at the bar again, only to find Kunieda there! And the president himself...?! Thinking back on last night's blunder and feeling in danger of being fired, Rika begged him, "I'll do anything, just don't tell anyone!" But what condition did Kunieda present to her?!
