女大学生木之下茜突然被男友提出分手，原因竟是男友喜欢上在线游戏认识的女网友。讽刺的是，茜当初配合男友的兴趣，也有玩同样的游戏。为了发泄情绪，她登入游戏胡乱打怪，碰巧遇见了同公会成员的山田。

在FOS的线下活动偶然遇见了「山田」的茜，不过，遇到前男友（带着新女友）的时候，冲动地脱口而出山田是她的新男友。 为了弥补山田，就带他去了一家居酒屋，茜喝得酩酊大醉，被山田被照顾并且丢失了回忆中的首饰的茜非常失态……。 茜为了找回首饰，在FOS的工会室遇到了山田。但是，被山田冷淡地对待之后，还对武器库的使用方法提出了不满。

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…

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.

Akane, who was now determined to confess her feelings to Yamada, reaches out to ask for advice from Momoko, the friend who consoled her after her most recent break up, and Rurihime, or rather Eita. As to not lose the momentum she got from that, Akane heads to Yamada’s apartment without any forewarning, but she had arrived just when he is rushing out of his home to get to cram school and can’t get herself to tell him how she feels. They decide to meet again after he finishes his lessons but are then met with a sudden rainstorm. Along with the rainstorm, Tsubaki also makes a sudden and impulsive action, which ended up leading to Akane and Yamada’s plans to meet up being cancelled…

与此同时，茜参加了公会的烧烤聚会。尽管山田应该也会晚一些会合，但茜因紧张而不知不觉喝得太多，结果喝醉了。在这种情况下，山田还是按时赶到，并陪伴着醉醺醺的茜。当茜酒醒后，山田采取了什么行动呢......
