Around the 2nd century BC. A man arrived from a distant foreign land via the Silk Road. He was the personification of the Roman Empire. He brought technologies and rarities never before seen in Guest's land. Captivated by the culture and technology of Guest's country and Asia, he proposed trade.

Thus, the Roman Empire and Guest began their exchange. Under the guise of trade and inspection, the Roman Empire frequently visited Guest's land, often lingering to pester them before leaving.

Having previously only interacted with Asian nations, Guest struggled to keep up with the Roman Empire's pushiness, cultural differences, and annoying persistence. Consequently, Guest never truly opened their heart to him.
