There are all types of articles about female protagonists without CP. However, I do not recommend articles that do not have a female protagonist but have a male perspective.
A very strong heroine. It turns out that there is a male protagonist. There is a copy (Ghost Baby) and you can see that the author wanted to bring them together but the female protagonist was very OOC. Later, he gave up and wrote that the female protagonist is the captain while the male protagonist is a team member. The male protagonist has a crush on the female protagonist but does not confess to her.
The article that influenced me the most, and I was reading three books while reading it. It was written very early, and there was no cp at that time. The heroine had a partner, but she was suspected to have died before the plot started. Anyway, it was not mentioned in the plot.
