I believe her! / Ore wa Kanojo o Shinjiteru!

Kensuke and Ayumi are in love and have been dating since high school. He is a hard worker and spends most of his time in the office. She is a second-year university student, belongs to a tennis club, and likes to drink sake. And what a misfortune, Kensuke has to go on a business trip for a whole month, but the couple can still be together, since Japan is not a big country and traveling from one city to another is comparable to going from St. Petersburg to a dacha, of course, all this is possible only on weekends.

In general, it turns out that on working days there is no one at home who pays for gas, bread, water, but there is the president of the tennis club Ayumi, who is good-looking and also his father is a doctor, which means he is rich. How can one not give in to such a person?
