CATDOLL: Is the official foreshadowing or coincidence of the production of the second season of "Monster Girl's Daily Life"

In the final episode of the July anime "Monster Girls' Daily Life", when the protagonists and their group were holding vegetables on the roadside, there was a billboard behind them with the words "niki kettei" (the romanization of the second season) written on it; but the official did not declare that this was the news of the second season of "Monster Girls' Daily Life", so is it just a coincidence? Or is it a foreshadowing by the official? It is still unknown for the time being.
