Kazuki, Yanira, and Eshana are friends who share an interest in botany. One day, they decide to visit a rare plant exhibition. Before they leave, Eshana mentions that she needs to stop by the library to return some books and will meet Kazuki and Yanira at the exhibition later. Kazuki gives Eshana the exhibition tickets to keep in her book bag because she trusts Eshana's organizational skills. When they part ways, Tariq, a mutual friend who is unaware of the plant exhibition, invites Kazuki and Yanira for a surprise birthday party for Eshana, which will happen while they are supposed to be at the exhibition. Excited about the idea, Kazuki forgets about the exhibition tickets in Eshana's book bag. Yanira remembers but assumes Kazuki has a plan to get the tickets from Eshana or has spare tickets. On the way to the surprise party, Kazuki suddenly remembers the tickets and realizes she has no way to get them, since Eshana will be going straight to the library and then to the exhibition. At the party, Eshana arrives and is surprised and delighted, but then she too realizes that since they are all at the party, no one is using the exhibition tickets in her bag. Knowing that the tickets are being wasted disturbs Eshana slightly, but she decides to let it go and focus on the surprise and her friends. The next day, Eshana asks Kazuki about the tickets, but before Eshana says anything, Yanira interjects, assuming that Eshana is unaware of the surprise party and has forgotten that they all were together the previous day. How does each person understand the situation regarding the exhibition tickets, and what does this reveal about their respective states of knowledge before and after the party?
Kazuki initially is aware that the tickets are with Eshana, trusts her to keep them safe, and forgets about the tickets once Tariq introduces the idea of the surprise party. After remembering about the tickets en route to the party, she realizes she has no way to reclaim them in time for the exhibition, indicating an understanding that her plan has been derailed, but she cannot address it as to not spoil the surprise for Eshana.

Yanira knows that Eshana has the tickets but assumes Kazuki has a contingency plan. This suggests Yanira trusts in Kazuki's ability to manage such situations, without necessarily knowing the details of Kazuki's thoughts. However, her assumption is proven false when Kazuki remembers the tickets too late.

Eshana, when parting for the library, is under the impression that following her errand, she will head to the exhibition with the tickets she is safely keeping. Upon arriving at the surprise party, she is taken off guard and happy but eventually reflects on the situation, understands that the tickets have gone unused, and accepts the change in plans by prioritizing the joy of the surprise party over the missed exhibition.

At the party, none of them openly discuss the mishap with the tickets to maintain the surprise. The next day, when Eshana brings up the tickets, it is an indication that she remembers the original plan and recognizes the error that occurred but is possibly seeking closure or a confirmation of understanding from her friends.

Yanira, misreading the situation when she interrupts Eshana, assumes that Eshana has forgotten about the party because she brings up the tickets. This suggests Yanira believes Eshana is either unaware of what happened or confused about the plans from the previous day. Yanira holding this belief indicates a lack of communication and a misunderstanding regarding Eshana's awareness of the situation.

Each person's state of knowledge before the party involves shared information about the exhibition plan and Eshana's library errand but diverges when Kazuki and Yanira learn about the surprise party. Eshana is unaware of the party and the resultant change of plans. After the party, Kazuki knows the tickets were forgotten, Eshana recognizes the situation and its outcome, and Yanira mistakenly thinks Eshana is still unaware, demonstrating diverse perspectives based on individual experiences and assumptions.
