You can't train every guards, I think you can train only additional guards? Like Demons, Merchants.
If you are looking for girl in ornesse that has to work in your brothel, then go from center left down corner.
I'm playing this game for long time and almost every time I play as female, but never happend that Zent get FMC pregnant.
I always get these scenes.
First they talk on street, later in Inn, next is sex scene in bedroom Mar x Mom, and you can join or not, later go to castle sleep for three days (skip days) go back to mom and I think she says she likes Mar and you can say I'm happy for you or I saw you, no matter you choose is good, go talk to Mar and give him your blessing to let him get your Mom pregnant, later go talk to Mom, she ask you did yoy give blessing to Mar to get Me pregnant, I always choose Yes, you deserve to be happy. Return to castle and again skip 3 days, if that won't work, do mini/side quest and return to Mom, another Mom x Mar scene will activate, talk to Mother, she says she is pegnant, If you play as Female after some time her pregnancy disappear and that's end. but if you play as Male go skip or mini quest and I don't remember correctly talk to Mar or Mom, she is in heat and you can fuck her with Mar. Sorry for long message. Hope it's gonna help
