Before the honeymoon period is over, the couple has entered the "old couple mode" . They have been invited to a New Year's Eve concert, and several established TV stations have asked if they can attend. The couple has agreed to go to the concert because it is the highest price offered by "lemon tv" , and because the price is higher than the cost of renting a new house. The new year has arrived, and since they want to have "a serious relationship," they have to buy a house. Since the stock market has gone up again, they have more money than before, and the couple is worried that they will not be able to afford the house.
