Izumi Miyamura/Relationships

Kyouko Hori
Hori is Miyamura's main love interest. Miyamura is shown to value Hori as a very good friend and she values him in return too. She is, according to Iori Miyamura (Miyamura's mother), one of his only friends since Primary School.

As the story progresses, he starts developing feelings for her. In Chapter 20, when Hori is sick and lying on her bed trying to sleep, he says "I like you" when he knew that Hori is actually awake and listening. He loves Hori's company and when asked by Kyousuke Hori (Hori's father) to cut his hair, he did not hesitate to, before being stopped by him.

She is the first friend Miyamura has made since high school has started. Hori first met Miyamura in his outdoor style, when he brought Souta Hori home after he fell due to a scary dog, but they also met during the beginning of their first year when Miyamura was with Kouichi Shindou. At first Hori didn't recognize that he was Miyamura, a classmate, but when she invited him into her house, he unexpectedly called out Hori's name. Hori was surprised that he knew her name, and when he said he was Miyamura. From that point on, they became friends and Hori has been friendly and open to him even though of his appearance. He often visits Hori and Souta at their home where he brings cake from his family bakery. Hori was the first person from his high school to see Miyamura in that appearance and he was the first person to see Hori in the "housewife" appearance. They wanted their "secret" appearance to be kept secret and that only each other knew what their other self was like. As the story progresses, they realize they like each other and Hori becomes Miyamura's girlfriend. In Chapter 37 on a rainy night, when they are alone together in her room she realizes how much she loves Miyamura and they decide to sleep together that night. After the realization sets in for Hori that they might be separated after this last year of high school, she tells him she still wants to be with him. Miyamura, in turn, asks Hori to marry him. As of now in the manga, they are engaged.

Later in the webcomic ending, it is revealed that they both got married (which now makes her Kyouko Miyamura) and they both have a son named Kyouhei Miyamura.

Souta Hori
Souta refers to Miyamura as 'onii-chan' and often clings to him when Miyamura comes over. He is a fairly independent and observant child, staying out of the house to try to let Miyamura and Kyouko Hori spend more time together. He seems to have some knowledge of sex as he asks Miyamura if Miyamura and Kyouko were always doing 'that' after finding his school pin on the floor. He is a picky eater, but she has since learned to be less picky thanks to Miyamura's influence and encouragement for him to try new things, but he still dislikes carrots. He is very protective of his big sister, Miyamura and the roles they play in his life.

Kyousuke Hori
Kyousuke is often excited about having Miyamura over and greatly enjoys his company. He supports the relationship between Miyamura and Kyouko Hori that he refers to Miyamura as his 'heir'. Even though he likes Miyamura a lot, he had some trouble recognizing Miyamura when he has his hair down and glasses on or when he cut his hair short. Miyamura prefers Kyousuke's company compared to the company of the other girls in his class who started taking notice of him after he cut his hair short. Miyamura refers to Kyousuke by his first name. It should be noted that Kyousuke has forced Miyamura to bath with him, thus scaring him emotionally.

Yuriko Hori
Miyamura is surprised at how young Yuriko is when he first meets her. She takes a great liking towards him and encourages the relationship between Miyamura and Kyouko Hori. She also often prioritizes him over her husband such as preparing food and tableware for Miyamura, but having none for Kyousuke Hori. Yuriko is grateful to Miyamura for helping out with Souta Hori and her daughter especially since she and her husband are both busy and often away from home.

Tooru Ishikawa
Tooru is Miyamura's first male friend in Katagiri High who is now one of his closest friends. He was hostile towards Miyamura at first because he was jealous of how close Miyamura had become with Kyouko Hori whom he had a crush on, but it is shown that he has changed his love interest to Yuki Yoshikawa later in the manga.

He is the only person in Katagiri apart from Hori that knows of Miyamura's tattoos or see Miyamura in casual clothing. At one point in the manga, they were trying to call each other with their first name, but Miyamura forgot about that and addresses Tooru formally as "Ishikawa-san" the next day. After finding out Hori likes Miyamura, he tries to get a response from Miyamura, but he ends up arguing with him. He is the first to know about Miyamura and Hori dating and cheers him on despite feeling heartbroken because he still liked Hori. After that, the two spent less time together, but he has since become close again. He is shown to be a good swimmer and worked part-time as a lifeguard during the summer. He likes sailor uniforms and after catching Miyamura wearing one once before asks if he will wear it again, then proceeds to imagine how Miyamura would look in a sailor uniform once his hair has grown out. He cares very much for Miyamura and sometimes worries for him.

Kouichi Shindou
Shindou is Miyamura's best friend since junior high, he knows all there is to know about Miyamura. They share an interesting friendship where Shindou views Miyamura as a close friend and devotes 30% of himself towards Miyamura while Miyamura doesn't hesitate to abuse and verbally attack Shindou. Miyamura is quick to drop his reserved and quiet demeanor around Shindou (even when there are other acquaintances around such as Tooru Ishikawa and Kyouko Hori) and shows a more darker, somewhat sadistic and cynical side of himself. After graduating from junior high, it seems that they lost contact for a period of time, however recently they seem to be hanging out together more often and Miyamura often calls on Shindou for advice. Shindou occasionally refers to Miyamura by his first name.
