The story of a contract marriage set in an old-fashioned goldfish shop. Asahi and Nana are newlyweds who run a goldfish shop. At first glance, they seem to be a normal couple, but in fact, they are a contractual couple who got married because of their mutual interests! They are not true husband and wive, let alone lovers. And yet... [I'm sorry. I know this is our first time meeting, but will you marry me?]

Do we hereby pledge to love and protect each other in health, in sickness, in curse, and in ugliness?

from cotton candy scans: Misaki, whose father is the president of a company, has always been alone despite leading a wealthy life. Her father has entrusted his capable subordinate, Miyashita-san, to look after Misaki! Even though Misaki is confused about living together with the handsome older man all of a sudden, he keeps his calm demeanour and says that "this is just work". But while living together with him, she started to notice her heart racing more for the slightly ditzy and very kind Miyashita-san… A rich lady x capable subordinate's 24-hour heart-racing love!! An age-gap, cohabitation love.
