My Love Story with Yamada-kun at Lv999

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.
