Ore no Yome: Anata dake no Hanayome

The game starts with you confessing to your girlfriend on the rooftop of your high school. You then get married and spend the remainder of the game spending time with your wife. You take her out shopping, go on dates to amusement parks or the mall, share dinner together, just basic newlywed stuff. There's special events which come up from time to time, like having a terrible day at work your wife will comfort you, getting in an argument with her, helping her cook dinner, and so on.
