Akane Kinoshita, a University student, was struck with tragedy when her boyfriend Takuma ended their relationship with the words, “I’ve fallen for someone else.” To make things even worse, it seems the other girl he fell for is someone he met through the online game “Forest of Savior (FOS),” which was a game that Akane also started playing in order to spend more time with Takuma. Unable to hold in her stress, she goes on to relieve her distress onto weak mobs in FOS. Then, YAMADA from the same guild happens to find her. She spills what she had just gone through with her now broken up boyfriend but has no idea that this is going to change her life drastically.

Akane, who attended the FOS offline event coincidentally finds YAMADA there. At the same time however, she runs into her ex-boyfriend (along with his now-girlfriend) and impulsively blurts out that Yamada is her new boyfriend. To amend the trouble she put Yamada though, she takes him to an izakaya where she then ends up becoming completely wasted. Yamada is left with no choice but to care for her at his home where he relieves her, but she also loses her treasured necklace there… In search of her lost accessory, Akane enters the guild hall and happens to see Yamada. However, not only is she treated coldly by him, but he also harshly reprimands the way she is using the guild storage space.

Unable to get over her break up, Akane is having trouble focusing on the match making date she was attending. She logs into FOS, where she happens to find the guild master, Rurihime, and Yamada. Although Yamada is usually completely inexpressive like a “Noh mask,” Akane realizes that he’s always been very close with Rurihime in their interactions. She begins to wonder if they’re actually in a romantic relationship, and this makes her start to realize her inner feelings. Akane then receives an invitation from Rurihime for an offline meetup, and they make plans to meet but…

Akane joins the offline meetup of the Chocolate Rabbit Guild being held at the FOS collab café. Though she’s able to recognize who Yamada and this Rurihime-like girl is, she struggles to figure out who the two others in attendance, Eita and Mr. Kamota, are. Seeing this, Yamada suggests they start with self-introductions, where Akane finds out that Mr. Kamota is a player with the username takezo and he is a strawberry farmer who she’s never come across in FOS. The other unknown figure, Eita, was the player of a character that Akane would never have guessed…

Although Akane really wanted to become friends with the members of their guild, she could sense that Eita’s younger sister, Runa, was putting some distance between them. She then receives an invitation from Runa to meet at a café, which makes Akane ecstatic. Little did she know this invitation was actually a prank Runa pulled on her, and the person who came to meet Akane at the café was actually a man and a complete stranger who is a self-proclaimed Rurihime fan. Akane excuses herself to the ladies’ room to organize her thoughts but… Meanwhile, Yamada who was visiting the Sasaki household to tutor Runa notices her strange behavior and soon finds out about the prank that Runa had pulled on Akane.

Thanks to the intervention of the guild members led by Yamada, the predicament caused by Runa’s prank was resolved. Akane also accepts Runa’s apology who takes such a liking to Akane that she starts to visit Akane’s home frequently. Now that the two had developed a good friendship, Akane also begins spending lots of time playing FOS, and finally becomes friends with Yamada in-game. However, after spending so much time playing the resource heavy online game on her laptop, it suddenly explodes--.

Yamada visits Akane’s apartment to help repair her laptop. After a certain experience he had, Yamada had been trying to get too close to women. However, for some reason, he just wasn’t able to take his eyes off of Akane taking an afternoon nap. He unthinkingly reaches out to touch her hair, but then he stops when he hears the doorbell ring. When Yamada goes to check the front door, he finds Akane’s ex-boyfriend, Takuma, standing there. Shocked to see Yamada coming out of Akane’s room, Takuma explains his reason for his visit…

Akane visits Yamada’s high school’s school festival, the “Higashinari Festival,” along with the other guild members. Eita and Mr. Kamota stop by to enjoy one of the student-run maid cafés, but Runa on the other hand begins to experience intense stomach pains from the pressure she was feeling around taking the entrance exams for this high school the following year. She makes a dash for the restroom, and Akane feeling concerned for her, stands in front of the restroom to wait for her. Yamada appears before her, and the two end up walking around the school doing some shopping later on. Upon seeing Yamada walking alongside a woman, the surrounding students begin causing a ruckus...

After hearing each other’s true feelings at the school festival, Akane and Yamada have become closer than ever. Although Akane now had more confidence in how she felt about Yamada, somewhere in her heart she felt needed to hold herself back. With her thoughts in disarray, she finds out a new development was occurring in their FOS guild. It was decided a new female member would be added to the guild. Moreover, this was actually someone that Yamada was introducing to them. And she was also his classmate…

Akane was about to collapse while going through a horrible cold, but then Yamada appears before her. Yamada picks her up and carries her to a nearby hospital. Meanwhile, noticing that he had missed his cram school lesson, his classmate Tsubaki, who recently joined their guild, starts to worry about him. Tsubaki had become acquainted with Yamada after playing against him in another online game and also knows why he avoids associating too closely with women. In her heart, she knew, “it would be horrible to fall for someone this cruel,” but she couldn’t help but feel Yamada was starting to mean more and more to her…

Akane recovered from her cold thanks to Yamada’s care, and she is finally able to log into FOS again. There she meets the new guild member, TSUBAKI, in her FOS avatar. The two go to challenge a boss battle straight away but are overcome by its incredibly "solid" defense. They reach the time limit, and unfortunately, the boss gets away. But after fighting alongside each other, Akane deepens her friendship with TSUBAKI. After logging out, Akane calls Yamada to ask him for advice on strategizing against this boss, which turns into a very long phone call. Once the call ends, Akane finds new determination within herself.
