We can see from the video he exposed that Jun-yup Koo is wearing a shirt and cooking for both of them. Then Xiao S asked a particularly embarrassing sentence. He asked his brother-in-law if he could unbutton his coat again. I think this is a little too much. This man is your brother-in-law, not your husband. If it's your husband, you can make him undress, but he's your brother-in-law, isn't he? And most importantly, he even asked his brother-in-law why he liked his sister, not him.
First of all, don't say they are both married. Even if they are not married, they are a little too inquisitive. Besides, he himself has been married for so long. I think it is really unacceptable to ask his brother-in-law. I don't know their views on marriage, love and family, but I think it is absolutely impossible for a normal family to make such a request. Of course, some people may think that I think too much. They may just get along better and then be more casual, so they will ask this question, but I really don't think they should. It doesn't make any sense, but it will make people feel sick.
