As Valentine’s Day approaches, Yumiko is back with another request for the Service Club! She wants to figure out a way to give Hayama some chocolate, but standing in her way is his well-known policy of never accepting gifts on February 14. Hachiman, Yui, and Yukino decide to hold a cooking class as camouflage for some sweet exchanges, but their plan may lead to some unforeseen results-including a reminder of the unspoken feelings among the three of them...

There's a new student council president, and the Service Club's first job for their new leader is to help set up a Christmas event with another school. The problems keep piling up, but Hachiman keeps taking on task after task by himself! What's going to happen to the relationship between Hachiman, Yui, and Yukino from here?

Hachiman Hikigaya is a cynic. He believes "youth" is a crock-a sucker's game, an illusion woven from failure and hypocrisy. Unsurprisingly, he's not the most popular guy. Meanwhile, there's Yukino Yukinoshita-brilliant, beautiful, and chillier than winter in Antarctica. Would you believe she's not exactly beloved by her classmates either? The unlikely pair gets forced into a club dedicated to helping solve their fellow students' problems. But will an ice queen and a screwup really be able to help anybody?

ALL GOOD THINGS MUST COME TO AN END The calendar reads March, but the buds of new hope are far from blooming. Yukino, Yui, and Hachiman are finally trying to articulate their feelings and act on them-but doing so means irreversibly changing their relationships. As much as they would like things to stay the same forever, a new day cannot dawn until the beautiful sunset gives way to night. If they want to move forward, they must put an end to this chapter of their lives. Before they even have time to worry, though, the credits start to roll...

The seasons turn to spring as the story plunges into its final arc! Hachiman and Yui share their thoughts with each other, and Yukino lays bare her own feelings in the form of her "final request." Meanwhile, Isshiki Iroha visits the Service Club with a request to jazz up the school graduation ceremony...with a prom! This time, Yukino wants to handle the job on her own, but things might not go as planned...

The start of winter brings trying times for Hachiman. There’s Iroha’s selfish request for a “date,” his little sis Komachi’s insistence on an overcrowded New Year’s shrine visit, and Yukino’s birthday on the horizon. Just as Hachiman and Yui are out shopping for the right gift, a chance meeting with Yukino’s sister, Haruno, lands them in a social minefield—one fraught with awkward family ties and a history everyone is reluctant to get in to.

Thanks to interference from Yukino’s mom, Yukino and Yui’s plans for a Soubu High prom face ruin. But Hachiman has an idea: What if he were to devise a fake prom plan to make the girls’ version look better and disguise his scam as a genuine proposal? Of course, there’s no guarantee this delightfully devilish scheme will work, which is why Hachiman will need all the help he can get...
