Amakawa Haruto/Relationships

Amakawa Yuki

Haruto's mother. After the divorce Haruto's father made sure he wouldn't know of her until he became a 20 years old adult. It was then when he was explained that his father divorced from her when he discovered that she cheated on him and that Aki wasn't his daughter. By Rio's story Hauto met with her mother just once after being explained the truth and it was then when Yuki told him that Miharu was still missing but and Aki was doing fine. Months later Haruto died without apparently having met his mother again or being able to confirm if Aki's safety was real or a lie his mother told for the sake of not worrying him.

Ayase Miharu

His childhood friend and first and only love. Until they turned the age of 7, Haruto and Miharu were childhood best friends and inseparable. Before their parting, Haruto promised Miharu they will see each other again and marry. Despite the separation, Haruto kept hard on his promise, trying to be a better man worthy of Miharu : he studied agriculture, martial arts, and general chores. After Miharu was teleported with his in-law family in a another world, Haruto was devastated and lost his raisin d'être becoming an empty shell. Rikka described him as distraught during this period before his death on Earth.

Sendo Aki

His little sister. Revealed later as his half-sister due to their mother's cheating. In better times, Aki and Haruo loved each other dearly, often playing together with Miharu. Everything changed when their parents divorced and Haruto moved to the countryside. Until volume 22 Aki felt nothing but a illogical hatred towards Haruto for not keeping his promises. After volume 22, Aki realized she was irrationally shifting blame to Haruto when he himself, was too young to do anything and has since stopped illogically resenting him.
