My Republican-Era Espionage Story Seems a Little Off

Emmmm… The heroine goes to the dock and knows that she needs to transform into a so-called night dress, but she still wears a hairpin that basically represents her identity. We don't know how we determined that the male protagonist and Mr. Gu are together. How did we determine the identity of the male protagonist? Then while she believed that the male protagonist and Mr. Gu were anti-Japanese, she also suspected that the male protagonist had picked up her hairpin and was here to arrest her... When the dock exploded, she believed it was the male protagonist. She didn't think it was Mr. Gu who was powerful, so she decided it was the male protagonist... Then she found a hairpin in small regular script that was suspected to be left by an educated woman in her notes, and then she determined that it was left by the male protagonist... So, why? Who can explain it...

Very exciting, no golden fingers, but really brave 👍👍

The male and female protagonists rush to each other in the flames of war, which is simply a crazy cp ceiling. There are also high-energy scenes one after another, and the sense of oppression is simply amazing. Author, please work harder!

Very good, the author writes carefully.

It's super good-looking, with a compact plot and ups and downs. It caught my attention, and the plot description is superb.

Is the ending he or be? Is there a male and female protagonist?
