The day before the wedding day.
Today Mel will return to her parents' house, Tanner Mansion, and stay there for one night. Tomorrow morning her husband will pick her up and bring her to W Mansion and they will have a wedding ceremony only attended by their close family and friends.
At night there will be a party held in the W Clubs which is located not far from W Mansion. This area is closed to the member club and will only be accessible to guests attending their wedding party. And, after the wedding party in the evening, they will fly their second honeymoon.
