Is this an engagement notice or something? Other posts seem to be basically the same as wedding invitations (I'm not sure, just talking about my opinion). If the woman is old-fashioned, it's best to write the posts vertically.
If it is an invitation, it is a red note written by the man, indicating the date of the ceremony, the date of marriage and other related matters one by one, and personally sending it to the woman's house to discuss the wedding with the woman's house.
