1. Yes Cesar is the ML
2. Second ML is Lucrezia’s brother
3. They’re not treating each other as siblings. They suck at pretending to be siblings, which is the reason why Lucrezia tried to get rid of her in the first, so I really am not bothered by that aspect at all. I was wondering how they’d solve it for the characters in the webtoon who believe three to be siblings since they’d have to reveal she’s a commoner afterwards, but it’ll be done in a believable enough way.

He isn’t actually the ML, right?? I hate that I became so invested bc I really like the FL but if he’s the ML that just makes me so uncomfortable with the sibling behaviour and such
