Ore wa Kanojo o Shinjiteru!

The young couple Kensuke and Ayumi have loved each other since high school. They have just started to live together. Kensuke is a hard worker, working in an office like everyone else, hardcore Japanese, trying her best to earn a new clothes dryer. She is a college student, a member of a tennis club, and she does not shy away from a lot of sake.
When Kensuke has to go on a business trip for a month, he has to find a way to get away from home. But in any case they are together as Japan is not a big country and going from one town to another is like going to the country house from St. Petersburg, and of course, all this is possible only on weekends.
On a weekday there’s no one at home to pay for gas, bread and water, but there’s the president of the tennis club Ayumi, who is a good-looking man and his father is a doctor, which means he’s rich. How can you not give him one?
