<report>The theme here is pretty usual. You got a wife that trying to pay her husband debt from his friend. By chance the husband put some spying app on his friend smartphone. And then you can peek on his phone every weekend. To determine what the content you get you must set a work schedule for the husband every Sunday.
The thing is you can't open the schedule window nor the devagame (spying app) freely. And the way to see the wife pov is only by a full week flashback ( other than the replay mode).
Other than that I like the way mikoto slowly softened to fukuda. The art is good and nice. The ending could've been better but it's good enough.
