Akuyaku Reijou ni Erabareta nara, Yuuga ni Enjite Misemashou! (Machi)

The mission of one of the country's biggest projects, "Prince Love Support Team," is to fulfill the love between the prince and his heroine, a country girl of different status. Melia Rose, the country's number one lady—and a bit of an airhead—is chosen to play the
"villainess" role that will spice up their love.

By a group of actors such as the "Villainess' Crony" who looks plain but is a classy young noblewoman, the "Prince's Crony" who is very attractive when he takes off his glasses, the "Stalking horse" who is very popular with the ladies, the heroine is bullied every day. But the relationship between the prince and the heroine does not seem to be making any progress at all...

What the hell is going on here?!
