Seishun Scans: "I'm sorry. I know this is our first time meeting, but will you marry me?"

Asahi and Nana are newlyweds who run a goldfish shop. At first glance, they seem to be a normal couple, but in fact, they're a contractual couple who got married because of their mutual interests! They're not true husband and wive, let alone lovers; and yet, Asahi gets easily flustered by Nana! She even has delusions about him naked?! At this rate, will they be able to keep their contract marriage intact?!
