Wataru met his fiancée Chika for the first time at a formal marriage interview. As strangers, they didn’t have any friendship between them, let alone feelings of love. They didn’t want to trouble their parents without any particular objections, but they were at a loss of what to do since they were both earnest students who had no dating experience.

While Wataru had no issues with the beautiful and seemingly flawless Chika, he believed that it was pitiful for a man to have his love chosen for him. He wished to be free to choose his own bride. In return, Chika said that since their marriage had already been decided and she had no issues with his parents, she would be willing to marry him. However, it would be rude to him and their future children if she became his wife without having any feelings for him. So, she suggested that they work hard to become “true lovers” before their marriage date. Swayed by her reasoning, he agreed with her proposition.

They promised to fall in love with each other, in order to ensure that their planned marriage will last. To this end, they created a “love diary” and try out the things which lovers do, like going out for a date, doing shopping while holding hands, cooking dinner and feeding each other, and much more. This is the first page of their true love.

The prominent Kitasono family's refined daughter. She is quite serious about her and Wataru's relationship, but has zero experience with both love and sex. At school, she is an excellent student. She appreciates kindness and honesty more than anything.

In order to live up to her family and Wataru's expectations, she keeps up a diary about her and Wataru's love activities. Due to her zero experience, she has only read about all kinds of things from girls' magazines she borrowed from her friends. She often tries mimicking the things she learned from them, and sometimes manages to surprise or catch Wataru off his guard.
