What is the name of the online novel? The heroine is the host and the hero is the architect. At the beginning of the story, the heroine entered the wrong hotel room and slept with the hero.

Landlord, your question is not very detailed, which may not help you, but I recommend a novel. The starting point of the Three Kingdoms Total War is similar to the type of subject matter you need. It's quite popular these days, and it may meet your needs.

The biggest feature of this novel is that there are many intrigues and strategies, which is very unexpected. Maybe you'll be interested.
