In my playtrough (I did not went back yet to try other things), you could only do the husband schedule and there were only two options, work or rest, if you work too much you spend 1 energy drink and you have a maxiumum of 2 energy drinks.
The husband, Yayuki, borrows money from his fishing club friend, Fukuda, and spends it with horse racing. Yayuki only works in a part-time job at a convenince store and his wife, Mikoto, starts working on a part time job at Fukuda's house. Her job is about real estate, she helps Fukuda with accounting, visiting and managing apartaments. Fukuda has erectile disfuction ans is married, but he feels sexually atracted to Mikoto. One day he sees that Yayuki has a huge debt with him, 2 million+ yen and see this as an opportunity to get sexual favors from Mikoto to decrese the debt. At first, he goes straight to Yayuki and asks for Mikoto panties to reduce the debt, but he refuses and decides that he will work honestly for it, so he starts making a schedule to manage the debt payment. But when Fukuda asks the same to Mikoto... That's the basic premise, but there are some subplots around this.
Strange, he already had all the assets for this. He probably will, since most players will miss this.
