If my sister really loved this middle-aged man in his forties and wanted to get my father's permission somehow, I would definitely support her even if my father vehemently opposed it.
Of course, if this was the case, the best I could do would be to persuade my father to think more about her request.
But my sister, who was standing behind my father, had a distorted face as if she was very dissatisfied with this situation.
So, I knew what her expression indicated.
'It seems like this middle-aged man is trying to force my father to marry my sister to him…'
As they say, love has no borders or ages. If one has a favorable feeling to someone of the opposite sex, they can confess freely.
Nonetheless, there are limits as far as proposing or marriage is concerned.
A middle-aged man in his forties cannot forcefully propose to a woman in her twenties if it was against her will. If he insists on it, he can safely be called an idiot.
