Preludge
The two would have a one-sided interaction as Hachiman was involved in a car accident, as Hachiman was hit by Yukino's family's car when he saved Yui's dog. Thus making Hachiman miss the first week of his new High School life.

Season 1
After reading Hachiman's work about high school life. His homeroom teacher, Shizuka Hiratsuka did not like Hachiman's global idea about how he sees youth and typical high school life. As a sanction for giving her such an idiotic essay, his teacher decides he should join the Service Club to change his way of seeing high school life in such a stereotypical way, this is where he met Yukino, the top student in his grade, also portrayed as the prettiest girl in the school from Hachiman's POV.

At first Hachiman and Hachiman and Yukino both were considered as frenemies, they tended to insult each other in every possible way, calling each other by nicknames (YukiPedia, Fishigaya, Mr. Most Hated Guy In The Entire School, Seriousnoshita, Ice Cold Princess...) even though Hachiman only tried to befriend her after relating to her somehow due to their similarities, he forgot about this idea after being quickly shut down.

They somehow managed to become friends after a little while, also thanks to Yui Yuigahama who was desperately trying to both make them talk to break the awkwardness after she herself joined the Service Club.

Volume 7.5 Part A
At the Service Club, the members are recruited by Shizuka to help prepare a magazine to  promote Chiba's growth and one of the sections is to make “Love and Marriage” more appealing to today’s youth. Shizuka mentions that she doesn’t know anything about marriage. While Hachiman brought up the idea to write some fake articles, Yukino states that they’ll create a wall of text that will take too much time. They’d shared other brainstorming ideas, but both admit they are clueless when it comes to relationships as neither of them thinks like normal high school students. They would later ask for Yui’s help to come up with ideas. They would later decide to create a survey for students about their thoughts on marriage. While going over the questions everyone would mocks Hachiman's answer for how much a husband should make, 10 million Yen. Yukino would make fun of how he thinks and how he has no friends and turns to bleakness into science, and his employment and future prospects are shaky. And has the eyes of a dead fish, which pisses him off, and states that the world has types of people who would give the same answer. After Yui returned after giving some students the surveys as they won’t if it came from Hachiman. Yukino would prompt that she’ll think that Hachiman was either a cult leader or a shady salesman which he agreed. After going over the surveys they would be disappointed in the answers being a waste of time. Yukino comes up with an idea to call in someone she knows that is skilled in taking care of useless dead-weight and performing housework. Hachiman is really excited to meet this person until Komachi shows up and Yukino proceeds to insult him. Komachi would decide to dismiss the surveys and suggests they refocus the project on how to be a better wife. Komachi has Shizuka, Yui, Yukino and herself compete in a contest to raise their "wife points". The contest first comprised a cook-off, after seeing Yukino’s dish which was a paella, Hachiman had a taste and it was good enough that he was at a loss for words. And after seeing what Shizuka cooked which amazes both Hachiman and Yukino. During the 2nd contest are a bridal quiz and all of the participants look at Hachiman as he plans to be a stay-at-home husband. And during the second question about Christmas that a husband didn’t save enough, Yukino recognizes someone she knows. And during the final question about a husband possibly cheating after writing their answers, Hachiman became scared about Yukino’s answer although she meant to add “for questioning” but believes it to be the same much to the worry of the others. During the third contest, was a runway for a wedding gown show. After seeing Yui’s dress and Yukino's turns she would come out in a slim gown with a face veil that Hachiman comments "can't conceal her angry nature", which she would ask Hachiman to repeat the statement. Later they decide to take a group photo but Hachiman and Yukino didn’t want to participate and were forced to take part in the group photo. On Friday Yui and Yukino ask if Haciman was done with his draft but he doesn’t know, even though he tries to be done on Monday. But Yukino was impatient that he is taking so long with his section and wanted to know when he will be done. She tells him to just hurry up and send her his segment before hanging up before he got the chance to ask of how he is supposed to send her the draft. As he doesn’t know her email address.

Iroha would try to explain that she had Hachiman cooperate with her for the coverage and she later has the club help will out the coverage giving them a camera from the Student Council. Both Yui and Yukino would decide to go and look at Hachiman who decides to also come. On Hachiman's next free day at Chiba, he spots Yukino noticing that she was early. Although she states that it is normal to conduct in society by arriving 5 minutes early. Later Yui would arrive, and Hachiman would accompany them, they would first go to a shopping mall but because Hachiman was uncomfortable being around women's stores, Yukino appears before him stating that he’ll get reported if he does anything suspicious although he wouldn’t do anything suspicious. She’s not surprised by how he tries to avoid something. Although she wishes that he doesn’t perform anything embarrassing since he’s with them.

After going threw the photos, Iroha wanted to take a photo of the Service Club and the members of the Club. But due to the arrangement of the members, Yukino was on the left side of Hachiman during the arrangement of the photo. Hachiman would try to get up but was stopped by Yui and Yukino, Yukino would state that Hachiman was being stubborn. Iroha would take a picture of the members of the service club.

Season 3
One of the biggest problems the Hachiman and Yukino were facing together with Yui was the fact that Hachiman and Yukino started feeling like they were in a co-dependent relationship with one another. Yui noticed through the seasons the feelings both Hachiman and Yukino held for each other but decided to ignore these signs to finally make her moves on Hachiman, getting her hopes up for nothing she indirectly got rejected, after trying to confess her feelings to him, Hachiman confirms his feelings for Yukino to Yuighama and asks her for advice. “I want to keep being involved with her” he says, he then accompanied her home and left a heartbroken Yui having lost all hope.

The major conflict of the last season then grew more intense as they both tried their hardest to push back against the idea and got each other as a result even more close. After lots of thinking, and a small discussion with his teacher Hiratsuka who is initially the reason Hachiman and Yukino met, he finally found the words he wanted to tell to her, Hachiman had enough of this co-dependency problem they were both facing and after returning home with Yukino, him and her had a deep conversation for the first real time in the season, because both were bluntly avoiding each other to forget about the feelings they were holding back. They afterward confessed their love to each other saying they want to devote their lives to one another from here on out. Whatever path the future holds for them, they want to be in each others life. They afterward became a de-facto couple, still leaving on their way some students suspicious about their relationship.
