Mars thought Emmelyn was indeed sick. That's why she was quiet all morning. Usually, she would comment on many things or discuss anything that came to her mind.
Mars always loved listening to her chatter and voiced his opinion a little. Their chat was always good.
Now, he understood why Emmelyn was so distraught when he intentionally avoided her and didn't want to talk with her, before her drunk confession.
She was expressive and liked talking. She would suffer if she couldn't really talk to people. Mars was her opposite. He loved quiet and didn't talk much.
He normally hated noise and talkers. The prince could only stand Gewen, who talked too much because the man was his childhood friend and he was used to Gewen's chatter for decades already.
As for other people? Not so much. They knew to keep their silence before the crown price.
