I'm posting my theory here just so that I can "I knew it" later if it turns out right. This is from version 0.3 so far.
Antonio is the one behind the assassination attempts.
Also... MC's father is the father of Cordia's children, making them his half-siblings. Just a hunch.
Antonio is the one behind the assassination attempts.
- He wants to kill MC but not hurt anyone else, consistent with all the assassination attempts.
- He has access to poison 1 specific plate but none other during the dinner.
- He explicitly ordered the mercenaries not to harm the girls
- He convinced Trino to take the fall because that guy is dumb loyal, but possibly he didn't know he'd be killed. Then conveniently killing him to tie off loose ends, with the easy excuse of "anger". Notice Cordia wanted him alive, "didn't allow you to kill him"
- Possibly because he's insecure of his future position, since MC is like some sort of kwisatz haderach chosen one.
- Meta: This is harem storyline. A guy other than the MC is probably gonna get in the way of the MC, and/or be disposed of by the MC.
