1. Popularity: This short story is based on the background of World War II + Hetalia fan fiction + fifteen questions adapted from thirty war questions + romance.
The only CP Puhun is Gilbert Beshmit (Prussia/Russia/Spain)
This short story has nothing to do with any three-dimensional things, and is basically an anthropomorphic setting.
2. You can think of this short story as a side story of Pu Hong's CP in "The Legend of the Years". Although I said that the CP that will appear in "The Legend of the Years" can only be Pu Hong, I am still not used to blatantly writing CP in Wo Wo Tu, so...
3. The background of the story is mostly WW2, mixed with memories of childhood sweethearts and a small amount of content from the Seven Years War/First World War/After the War...
4. It's actually hard to say what the relationship between Puhong and Pu Hong is... After all, one of the (abuseful) points of this CP is the existence of a Chinese-European couple. The setting is probably that Kil and Isa have fought, kissed, quarreled, and quarreled, and they should have gotten over it... This kind of setting is mixed with complex alliances, love and death, and childhood sweethearts.
The author Pu Hong believes that if you see something that seems to be some other CP in it... It is an illusion, an illusion.
