Nach dem Vorfall mit Marcia ist Isla verletzt und muss zur Wartung. Als Isla in das Büro zurückkehrt, stellt sie fest, dass sie Tsukasa mehr Aufmerksamkeit schenkt als zuvor. Sie erzählt Michiru und Eru von ihren Gefühlen, doch sie verstehen diese falsch. Als die Nacht hereinbricht, stellt Isla fest, dass Tsukasa immer noch im Büro ist – sie leistet ihm Gesellschaft.
Three years ago, it is revealed that Isla began blaming herself for not accompanying Kazuki when she retrieved Michiru's father, which wound up costing Kazuki her ankle. As a result, Kazuki retired from her position as Isla's spotter. In the present day, it is revealed that Marcia was hit by Tsukasa's device, although Isla was able to block most of the blow without being hit herself. With Isla now under maintenance for her injuries inflicted by Marcia, Tsukasa is reassigned to desk duty. After a visit from Tsukasa, Isla notes that he is still remaining optimistic despite what happened and privately questions his feelings about the situation. Once most of her maintenance is done, Isla returns to the office and realizes that she has been paying attention to Tsukasa a lot more closely lately. She confides in Michiru and Eru about it, although they misinterpret her feelings as being motivated by love and Eru decides to help Isla stalk Tsukasa. However, after multiple attempts at observing him fail miserably, Isla confesses to Michiru about her confusion on Tsukasa's unwavering optimism. Michiru then tells her that Tsukasa never forgot about the incident with Marcia, even neglecting his desk duties to go and apologize to Souta for what happened, and assumes that he is smiling out of sadness. After finishing the last of her maintenance, Isla returns to the dorm, only to find he isn't there. When night falls and Tsukasa has yet to return home, she goes to the office, where she finds Tsukasa learning that she has 1,000 hours left in her lifespan, which translates to a month. However, when given the chance to partner up with a new Giftia, Tsukasa declares that he wants to remain partnered with Isla, which makes her happy.
L'affaire Masha est close et le service se remet doucement de ses émotions. Tsukasa, fraîchement arrivé, encaisse tant bien que mal, ce qui ne manque pas d'intriguer Isla.
