Do I need to choose a date for my first visit to the man's house?

I'm glad to answer this question for you. I saw your description of the problem. My personal views and my suggestions to you are as follows. First of all, describe the day when you first went to the man's house. Did you see your description of the problem? First of all, you don't need to choose the day to go to the man's house. Then, regardless of singles and doubles, if you say there are fixed rules and customs, you must go to the man's house on two days. Then you can understand. If your family doesn't have this custom, I think you can go to the man's house whether you are single or double-employed, as long as you are both happy.
