Max was abused by her father (still nobody fucking knows about it) and she was married to a commoner knight, who then went to war on her father's orders. He comes back and takes her to his fief, where he gets to know her better. At first he thinks she's scared of him, but then finds out she's just nervous and stutters since childhood.
War arc. Ch 125. Riftan finds out she came after him, helping injured people near the battle.
