Bottom-tier Character Tomozaki Analysis(13)

In the novel, Kikuchi has shown in many places that she seems not to be confident enough about her relationship with Tomozaki, especially when she knows what has happened between Tomozaki and Hinami. In Volume 9, Kikuchi’s word when receiving the old school badge attracts my attention:
旧校舎の旧校章。これってやっぱり……まるで友崎くんと日南さんのためにあるように思えませんか？
I understand that this can be considered as a joke based on the context. At first, I think the plot of using old school badges is just to bring the relationship between Tomozaki and Kikuchi to another level. However, I cannot help wondering the reason for telling readers that old school badges can be seen as an epitome of the relationship between Tomozaki and Hinami. If 屋久先生 did not explain that in the novel, most of people would not notice the underlying meaning of old school badges to imply the relationship between Tomozaki and Hinami. Another thing that deserves to mention is that this happened after Tomozaki and Kikuchi kissed each other. Honestly speaking, I do not think 屋久先生 will imply that for no reason. And this sentence is exactly the reasons why I think Ending 2 is possible.
