A Husband By Trust

One day, a suspicious man, Livius, appeared in front of her and gave her a parchment containing an oracle... Even when she sees the parchment that says she is the bride, she is embarrassed to tell him she is the bride. She does, but she doesn't tell him he's the bride, and he takes off her tack and she sends him back. But why did he deceive him and came to him? He begins a dubious contractual marriage to him and hers. (by Google Translate)
