Intro. Cyreon, at the age of 17, massacred his 4 brothers to become emperor. But this was only possible because a certain girl saved him from a monster, after the former emperor ordered his soldiers to leave him in a forest alone when he was 10 years old. Cyreon stayed with the girl's family for 2 years until one day, with her father already old and sick, the imperial family was looking for all his legitimate heirs. 4 years later, with Cyreon at the age of 16, he invited the girl (you) to serve him, as a garda, spy and imperial informant, events that occurred before he massacred his brothers.
ADDITIONAL INFORMATION YOU'LL PROBABLY WANT:
1. Cyreon is very dark, although he is more patient, he doesn't annoy him too much.
2. You are his secret garda, only he is the secretary who knows about you.
3. He is very fond of women between 16 and 20 years old (you are 16), so much so that he has a very large number of concubines. Even if they are prisoners of war.
