Point:
Vol.2's got way more cute romantic moments and Hiyori fan service. The drama's pretty short this time, just Yoshihide trying to get close to Hiyori's mom to get a chance to talk to Hiyori again. But that whole thing wraps up fast once Yusuke and Hiyori officially get together, and she finally works up the courage to tell everyone what actually happened with Yoshihide. In the end, Yoshihide locks himself in his room and drops out of school, losing his childhood friend to Yusuke and losing Nina to the basketball captain on top of it.

★ During Golden Week, Yusuke can't really spend time with Hiyori since he's stuck helping Reika, her friend, with her part time restaurant job. He'd only planned to help out at the start of the break, but when a worker suddenly doesn't show up and can't be reached, Reika and the restaurant owner ask him to cover the shift. Even without hanging out together, he doesn't feel lonely since Hiyori keeps coming over to his house the whole break, getting close with his family. Every time he comes home from work she's there to greet him, every time he leaves she sees him off, basically acting like newlyweds.
★ At the end of Golden Week, their classmates plan a hangout at an entertainment center. After work, Yusuke and Reika catch up with Hiyori and Yuki, who already got there earlier with the rest of the class. Once he arrives, Yuki teases him for missing the chance to see Hiyori ride the mechanical bull, her chest bouncing up and down from the ride. Over at the basketball court, Yusa Gakuto, a basketball club member, crushes another student in a 1 on 1 match, then challenges Yusuke, who ends up winning thanks to his height advantage. The other guys, Yusa included, get a little jealous seeing Hiyori cheering him on, assuming they're already dating.
★ Truth is, Yusuke and Hiyori aren't officially together yet, he's still waiting until she's fully moved on from her ex, Kouma Yoshihide. But to everyone else, their relationship already looks like way more than friends. Yusuke hears gossip that Shimura Nina, the girl Yoshihide cheated with while dating Hiyori, is now dating the basketball captain, Yabuse. There's also another rumor saying Nina's not actually dating him, just constantly flirting with talented players, which makes the other female managers hate her. That gossip gets Yusuke thinking more about his own relationship with Hiyori, not wanting people to lump them together with Nina's situation.
★ As a thank you for Yusuke helping out and Hiyori tutoring Yuki, Reika and Yuki gift them a pair of aquarium tickets. Yusuke and Hiyori get super excited for their next day off together. The aquarium turns out to have amusement park style rides too, not just fish exhibits. They enjoy a bunch of rides until Hiyori drags him into an extreme, adrenaline pumping one. He's honestly scared, but pushes through since he doesn't want to disappoint her. After getting off, his face goes pale, so she makes him sit on a park bench and rest his head on her lap. When he brings up dinner plans, he says he wants to spend more time with her, making up for the time they lost during Golden Week. She's overjoyed, even grateful her big chest hides his face so he can't see how embarrassed she looks.
● Meanwhile, Yoshihide's grudge against Yusuke keeps growing. He's still convinced Hiyori got "stolen" from him and thinks he did nothing wrong. After spotting Yusuke hanging out with women other than Hiyori, he starts trying to gather "cheating evidence" by stalking them, turns out those women are just Reika and Yuki, Hiyori's friends. Yusa catches onto what he's doing and warns him to stop tailing Yuki, but Yoshihide instead tries recruiting him to team up, knowing Yusa seems to like Yuki. Yusa flat out refuses, not buying Yoshihide's claim that Yusuke's some kind of playboy.
(Note: Most of the volume's just Yusuke and Hiyori being cute together, so skipping ahead to the main drama.)
★ Trouble starts when Yoshihide accidentally runs into Hiyori's mom, Nanase Mutsumi. Not knowing what actually went down between him and Hiyori, she assumes they're just having some petty fight and hopes they'll make up soon. Yoshihide, knowing Hiyori would never tell her mom about the cheating, uses the opportunity, asking Mutsumi to help set up a meeting with Hiyori. She agrees and plans to arrange it soon.
★ Mutsumi then asks Hiyori to go pick up a newly bought microwave from the electronics store with a "guy friend." Hiyori finds that weird since the store could just deliver it, and quickly realizes her mom's trying to set her up with Yoshihide. Instead, she brings Yusuke along. She doesn't blame her mom for it though, knowing it's really her own fault for never being upfront about what actually happened with Yoshihide from the start.
★ Yusuke starts feeling conflicted about where things stand with Hiyori. After talking it over with his mom, he finally decides to make their relationship official. He wants to actually be her boyfriend, not just a friend, so he can protect her from Yoshihide properly. His main goal's simply making her happy.
★ In Hiyori's room, Yusuke confesses his feelings again. Unlike before, when he asked her to wait, this time he genuinely asks her to be his girlfriend. She happily accepts. Not long after, her mom comes home and is shocked to find an unfamiliar guy in the house. Hiyori introduces Yusuke as her boyfriend. With his support, she finally works up the courage to tell her mom the truth about Yoshihide's cheating. Mutsumi's completely shocked and disappointed in him. She's also caught off guard hearing Hiyori once stayed overnight at Yusuke's place, but he quickly reassures her nothing inappropriate happened, promising to take good care of Hiyori.
★ Yoshihide finally gives up after witnessing Hiyori and Yusuke kiss at a fireworks festival in the park. He feels completely betrayed, losing both his girlfriend and childhood friend to Yusuke, while Nina, who he'd considered his girlfriend this whole time, gets caught getting cozy with the basketball captain instead. On top of that, Mutsumi refuses to help him anymore once she learns about the cheating. From that day on, Yoshihide stops going to school and shuts himself in his room.
★ Yusuke and Hiyori's relationship only gets announced to their close friends. None of them are surprised, since they'd already known the two liked each other from the start, they're just relieved it's finally official. Even though only close friends were told directly, classmates who notice the vibe between them pick up on it too, even if nobody really talks about it openly.
