As days passed, their cohabitation life gradually started to feel like that of a real couple. Hazama began turning down after-work drinking invitations and making excuses to his suspicious colleagues so he could head home early. Akane was already home, wearing her school uniform with an apron while cooking dinner. After the meal, while eating dessert, Hazama teased Akane about gaining weight. Feeling a bit self-conscious, Akane began thinking about dieting. Hazama then suggested having sex as a form of exercise that would feel good for both of them.
