Deep Love Diary -Koibito Nikki-

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.
