Due to his good looks and kind personality, he is extremely popular among both genders, especially the girls, much to the envy of some boys in the school. This is confirmed by many admiring girls surrounding and cheering him, not to mention in some occasions trying to impress him, like Minami Sagami, Yumiko and Iroha. Girls frequently blush in his presence and when they engage in a conversation with him.
Hayato's father is a lawyer and his mother is a doctor. So far, they are not officially introduced to the audience. His maternal grandfather is a family doctor to his father. He seems to have a close relationship with his parents. During the summer camp arc, he mentioned that both of them gave him a lift to Chiba Village summer camp. Yukino has never heard of Hayato going against his family's wishes. His career path choice is affected by his relationship with his parents.
Family Friends Edit
Hayato is known to have a good relationship with the Yukinoshita family. His father is the legal adviser for Mr Yukinoshita. Their families are mentioned to have a feast together during New Year and Christmas. According to Yukino, her mother wishes to have a long lasting relationship with Hayama which she believes will affect Hayato's career choice. But there is more than one way to continue the family friendship other than work, which Hachiman concludes as marriage.
Mrs. Yukinoshita was shown to address Hayato by his first name and formally she apologize to him, for making him wait for the feast. She states that she doesn't know any other classmate of Yukino other than Hayato while meeting Yui & Hachiman.
There was an incident involving them in the past resulting in their current strained relationship. Yukino's cold and curt demeanor towards him that shows she hasn't been able to forgive him.
They finally reconcile somewhat at Hayato's victory party for the marathon. Hayama also noticed Yukino's change of personality. And that she no longer closely follows her older sisters path. In episode 12 of season 2, Haruno mentions that Yukino once gave valentines chocolate to Hayato, but he added that she gave it to both himself and Haruno. Even though they have known each-other for a long time they address each other by their last name. In Episode 10 of season 2 (adapted version of Volume 10) Hayato accidentally addressed Yukino by her nickname, Yuki-chan, hinting that he still feels close to her.
Yukino may be the "Y" that Hayama mentioned he had a crush on.
CliqueEditHIs friends/Clique are Kakeru Tobe, Ōoka, and Yamato. Along with them, his clique includes Yumiko Miura, Yui Yuigahama, Hina Ebina. He is also friendly with everyone outside his clique.
Hayama deeply cares about his friends and also tries to prevent his clique from breaking down at multiple points in the series. However, for the most part he failed in solving his clique's problems, especially during the moment when Tobe wanted to confess to Ebina. Due to his conflicting feelings on the matter, he reluctantly asked for Hikigaya's help in solving his group's problem.
His clique is mentioned to be most popular and dominating throughout the school, especially in Class 2-F. They often hangout together and chat in free times. His clique contributed to both class play and ending ceremony of the Culture Festival. During the Athletics festival the majority of his clique were in Team White, with the exception of Yuigahama, who was in Team Red.
However, Hachiman suspects that they only appear to be close and if their relationships were deeper they wouldn't get along well. Hayato mentions to Hachiman that that the clique is all he has and wants to maintain the clique's status quo. Although Hachiman direclty accused to Hayato that his clique is superficial, Hayato felt otherwise.
Yumiko shows jealousy towards every girl who approaches Hayato which is shown on the double date incident with Kaori. She is greatly disturbed by the rumors revolving around Hayato and Yukino. Despite being close in their clique, there are topics which Yumiko cannot ask or Hayato refuses to answer in his own way, examples of which being his plans for Christmas, or his future career path, and others.
She also can't stand anyone badmouthing Hayato which leads to the hostile behaviour towards Yukino in the Chiba summer camp and also against Saki during the Tokyo visit.
Both of them call each other by first name. But Hachiman accuses Hayato of using Yumiko to avoid other girls in an attempt to provoke him which is still unanswered by Hayato. Hayato's true feelings of her are unknown.
Nothing much about their interaction is shown onscreen to the audience, but there are hints of Hina requesting Hayato's help in stopping Tobe from confessing.
Hayato and Yui call each other by first name. They occasionally exchange messages and have each-others phone number. They view each other in a positive light. Hayato also went along with Yui's request to help with Taishi's request. Both Hayato and Yui have similar traits. They are cheerful and kind to everyone but both have mentioned to Hachiman they aren't as nice as others think.
Yui may be the "Y" Hayama mentioned he had a crush on.
Soubu High SchoolEditEpisode 10 of season 2 (adapted from Volume 9) she even confessed to Hayama in Destinyland. Hayama rejected her, most likely due to his "neutral" stance on everything. Hayato mentions to Hachiman that he was happy about her feelings for him, but suspects they were meant for someone else. However, even after the rejection, Hayama and Isshiki remain companions.
Hayato also mentions Saika to be popular with girls, at least equal to him.
Due to his own mistakes in the past and his inability to make a difference in crucial moments, he begins to feel inferior to Hachiman because of the ability Hachiman has to change the people around him. Hayama Hayato shows shades of his true personality whenever he talks privately with Hachiman because he thinks that Hachiman is same as him even though Hachiman himself rejects the idea.
Yukino describes Hayato as the antithesis to Hachiman. While Hayato is kind and outgoing which causes people to be around him very often, Hikigaya is not and keeps all of his words to himself, causing the opposite effect to happen. Furthermore, their methods are very different. While Hayato seeks to maintain the best of both worlds so that both parties may succeed in problems, Hikigaya only cares about getting the job done, regardless of the price that he needs to pay. Hayato's methods often fail and Hachiman's succeed.
Hayato also is saddened and disappointed by the methods that Hikigaya uses to solve issues, due to the fact that he repeatedly self-sacrifices himself to actually solve them. As pointed out by Yukino, his methods do not actually solve the problem in hand, only alleviating it. He tried pointing this out to Hikigaya during the double date and yet, Hachiman refused to change his mind.
Hayato knows about Hachiman's past crush on Kaori, and surmises that neither of them have actually fallen in love.
Like all other females in her school, Minami is interested in Hayato. Sagami tries appealing to Hayato. However, he sees through her innocent facade.
It should be noted that Hayato only followed Tobe's recommendation of Sagami for the Culture Festival class rep and did not directly recommend her. Again Hayato recommended her to the Athletic festival planning committee only after witnessing Yukino, Yui and Shiromeguri's futile attempts to get Sagami to take up the role.
Even though Hayato doen't view Sagami in good light, he doesn't show it at face value and has always acted in good faith towards her. He also stood up to Hachiman for her.
Hayama showed his cold side to Kaori and her friend for belittling Hachiman and told them not to judge a book by its cover. They ended on bad terms and haven't met again. In the light novel Kaori expresses to Hachiman the difficulty, but desire to seeing Hayama again.
She is a friend of Kaori and was interested in Hayama. There are no details of them exchanging contacts, but she also went on the double date where she tried her best to appeal to him. By the end of the double date she seems disinterested and off-put by Hayama's cold side.
