Synopsis
'''Is it only the counselor who has a reason to visit? Interracial marriage is tough!''' "Freedom means that elves and dwarves love each other without being punished." After the end of the inter-species war, the 17 races established an experimental city, Myis, for all humans to live in equality. A few years later, many different races visit the marriage agency that claims 100% customer satisfaction in this city. An apprentice staff member, Anya, who is from the cat race, works day and night to make connections with the clients under the mysterious beauty of the director, Donna, along with the scumbag instructor, Shaw. What Anya longed for was a wonderful job where she could support happy encounters between people of different races in this free city... but in reality, she spent her days dealing with people who had problems! "An elf girl with high ideals (three centuries without a boyfriend), a gentle man who destroyed an S-rank party with her troublesome abilities--but no matter how many quirks she has, she's just too strong!" ? "The slapstick marriage fantasy begins!" ! ! !
