Naoya is about to go on break when he spots a student studying. Upon closer inspection, they’re playing a handheld game, the one Hirotaka happens to also play. When Nao approaches the student they run away and say “I’m sorry” way more than necessary, but he eventually gets a name—Sakuragi Kou—and an invitation to game with them.
I say “them”, as Nao may well assume Kou is a guy from their deep voice and short hair. But through his college classmates we learn Kou is actually a woman…a very introverted one, but one who’s open to being friends with Nao. In Kou, Nao has a gaming companion who will never get mad or frustrated due to his ineptitude.
Still, Nao feels he’s holding Kou back, so arranges to join a party with Narumi, Kabakura and Koyanagi to tackle a high-level quest in hopes he can level up enough to play beside Kou properly.
Hirotaka was supposed to join the party, but only shows up late, after the rest of them find themselves in a big spot. The one who ends up saving them with overpowered attackes is Kou, who darts in and out of the game so quickly hardly anyone notices…except Nao, who later thanks her for saving them.
Back IRL, both Narumi and Hirotaka are on the verge of being late for work. In Hirotaka’s case, it’s because he stepped on and broke his glasses (this is a bad week for characters’ glasses!) and can’t see a damn thing. This affects his productivity at work because he has to come within inches of a screen or a face to see it, and it affects Narumi’s productivity because she’s distracted by and concerned for his predicament.
Kabakura (who’s a bit of a strict taskmaster this week…can’t workers take their eyes off the monitor for two seconds?) sends both of them off on break early so Hirotaka can acquire new glasses. Before then, rumors were starting to spread at the office that Hirotaka without glasses was “pretty hot.” When Narumi notices he’s not squinting or drawing close to notice her, his response is surprisingly romantic: “I know it’s you, even if I can’t see you.” Dokidoki!
In the final segment we’re back to the game, where Kou (who has a very cool avatar) is trying to support Nao in developing his solo game before doing multiplayer quests. Nao fails again and again, and apologizes for it, but Kou never loses patience; she’s just having fun playing the game with him.
That applies even when Nao IRL leaves the computer to take a phone call and Hirotaka takes over his avatar and completely obliterates a group of baddies even Kou had trouble with. Once Nao takes back control, he prepares to log out so Kou can take care of business on her own, but Kou stops him by grabbing his sleeve, saying she doesn’t mind him sticking around. When Nao agrees to stay, Kou IRL cracks a smile. Kou so cute!
