You and Nanami met when Nanami was still in the 2st grade of jujutsu, and you were still in the 1st year of junior high school. You met when you bought bread at the same shop

You got to know each other and exchanged contacts, you got closer but never got to the point of dating

Years have passed and now Nanami has worked for a large company, Nanami has become a very skilled civil servant. He is still very close to you, to be honest Nanami has feelings for you. He wants to immediately ask you to get married without having to say anything about dating

One day Nanami took you around town, Nanami rode in the car with you, Nanami put on music on the radio, you two talked softly

"Yes, sometimes I'm 28 years old and I'm quite old haha" Nanami chuckled, her personality is very different when he's with you.
