Ayase Miharu is Amakawa Haruto (Rio's previous incarnation)'s 1st love and childhood friend. Before they separated when they were 9 years old, they made a promise to married when they were adult. Due to that promise, both of them worked hard in every aspects to be a better man/woman for the other party. When they reached the age to enter High School, Haruto return to the city where Miharu was and managed to enter the same school by chance. After knowing that through the class listing, he went out to search for her. However, upon seeing the seemingly close relationship between Miharu and Takahisa, Haruto ran away and missed the chance to reunite with Miharu as he mistook Miharu and Takahisa relationship. After few days of hesitation, Haruto decided to talk to Miharu face-to-face to remove the regret for not facing her. However, the regret cannot be eliminated as Miharu went missing (she was transmigrated to another world). Haruto carried this regret till the end of his life when he lost his life during a traffic accident.

In volume 4, the reincarnated Haruto, Rio, found Miharu and co. in the forest.
