Haruno's father is a member of Chiba's diet and also the CEO of a construction company. She sometimes acts as her father's representative in public events.

Mrs. Yukinoshita (Mother)
Voiced : Kikuko InoueHer mother was introduced in season 2, Episode 10 (adapted from Light novel Volume 10, Chapter 2), where she came to meet Haruno, Hayato and Yukino to their family holiday dinner. Haruno mentions in Episode 9 that her mother is scarier than herself and makes all the decisions for the family. In Season 2, Episode 11 (Adaptation of Volume 11) Haruno was ordered by her mother to stay at Yukino's house.
However, Haruno cares about Yukino in her own way. Despite putting on a cold face in front of Yukino, she sometimes almost breaks to the point where she shows that she is actually regretful for making things end up in a way where Yukino thinks of her as someone who poses a challenge to her own life.
They have contrasting names, Haru means spring and is associated with warmth. While Yuki means snow.
Being the eldest child of the Yukinoshita's, she was taken around for work related courtesy visits or parties. Making a lot of acquaintances during this time.
Hayato family has a business related relationship with Yukinoshita. As result Haruno developed a decent relationship with them. According to Haruno, Hayato's parents were affectionate with her and Yukino, almost like family. Yukino doesn't quite agree.
Soubu High School
She is an alumnae of the school and has made a lot of acquaintances in the school. She often visits for various reasons. She volunteered for the Culture Festival on her own motives or from persuasion by Shiromeguri and performed with her musical orchestra.
Even though they have a teacher-student relationship, they call each other by their first name. Haruno can see the kind-hearted motherly nature of Shizuka and can predict her motives, as she was able to see the reason behind Hachiman's participation in Cultural committee.
It was later hinted that she also knows about the car accident that involved Hachiman, Yui, and Yukino. After the Culture Festival, she congratulated Hachiman for his bravery during the confrontation with Sagami, and admired him for it. Haruno calls Hachiman a "Monster Of Logic" because of his critical analyzing of peoples behaviours.
Haruno also sets-up Hachiman and Hayato on a double date with Kaori Orimoto and her friend.
Haruno's first impression of Yui is very demeaning, as Haruno warned smilingly that Yui should stay away from Hachiman, as he belongs to Yukino alone.The second time they met was at the Fireworks Festival. After hearing that Yui is Yukino's best friend, Haruno advises her not to leave Yukino like her previous peers, to which Yui replies seriously that she won't abandon Yukino and loves her as a friend. Haruno also expresses her concern that if Hachiman were to choose Yui, Yukino would "lose out" again.
Iroha made her acquaintance during the pre-valentines day event (in the anime). Iroha tried to appeal to Haruno which Haruno sees through.
Shown neither on-screen nor in the light novel, it was mentioned they sometimes meet or exchange messages. It was shown that they exchanged contacts with each other as a way for Haruno to keep in touch with Hachiman. It was also mentioned in the light novel that they exchanged their contacts during the Cultural Festival of Soubu High. Haruno also wishes to have Komachi as her sister. Both of them seem enjoy pressuring their siblings into relationships.
The only time they were shown together was during the time the Service Club members returned from the Chiba village, where Haruno was waiting to take Yukino home to their mom in Episode 8 of Season 1.
Haruno also learned about Hachiman's past and confession to Kaori from her. Haruno also introduced Hayato to the girls. She indirectly set the stage for the double date and followed them without their knowledge throughout their date, as she felt that things were amusing. Haruno also wondered about Yukino's reaction, if she learned about Hachiman's confession to Kaori.
