In order to avoid marrying an old man from the neighboring county, she must run away. The first time she escaped, the general entered the city, and she rolled and fell in front of him, no, she kneeled in front of him (really not on purpose). The second time she escaped, the general came to visit her house, and the general caught her (he must have done it on purpose). The third time, she was bruised and battered, almost desperate, and he came galloping and took her into his arms. (He was very well-intentioned.) The general said, ” Although I do not want to hold a favor to you, it is true that you owe me a favor.” So?
