Tsurumi and Wilk were playing house by marrying and forming a family with the women they loved, endangering the mission they were set on.
The difference is that no one knew of Tsurumi’s play, where he assumed a different demeanor and identity as Koichi Hasegawa for his spy activities yet genuinely loved Fina and Olga, unlike the theater play he would impose years later on his soldiers, people he perceived as sheep, under his true name to exact his revenge on Wilk and achieve imperialist cause for Japan
Meanwhile Wilk fell in love with Riratte and had Asirpa with her under his real identity, shifting his revolutionary goals instead to a mission of establishing Ainu independence for his daughter, even if that meant unorthodoxly raising her to be a revolutionary symbol. But to Kiroranke, Wilk’s family and shifted goal was was a betrayal of the sacrifices Sofia and their comrades made for their partisan mission/revopution.
To summarize, Tsurumi’s life with Fina and Olga was a play, but something he cherished, with no one knowing. While Wilk honestly built a home with Riratte and Asirpa that Kiroranke saw as him playing house.
