Hi, resuri! Super happy you decided to give my demo a go, and even more that you enjoyed it
The way it works is that there are flags for either if you’ve encouraged romantic connections or discouraged them. IF you have done either - not flirt or remain oblivious - then Alessa and Hadrian still have a crush on the MC (if you have a high friendship, of course).
If so, they will approach the MC (or keep awkwardly trying to approach you) or you will have further opportunities to begin the romance.
So, long story short: Absolutely not! You shouldn’t have to jump at the first flirt option to be able to romance a character. If you decide to wait, the romance itself will move at a slower pace.
Hope that answers your question!
I’m glad you don’t mind being a mercenary. The MC’s circumstances and how they got to where they are will be explored in the future.
I can’t really comment about keeps and generals, however. I’ll leave that to your very vivid imagination
