He's right behind the 2nd princess
It is hinted that there's a traitor in the knight ranks during the war. And I'm pretty sure it's him, probably because he was trying to find his wife (first princess) and was manipulated into it. Now, whether he's has helped the 2nd princess too much or he's just evil from the start, he is on her side.
Unless you're talking about someone else ? 1st princess is with this redhead knight
2nd was supposed so marry the ML
3rd was married to a noble from another country iirc
I forgot since it's been so long since I last checked on this biut what happened to the sisters fiancee again? The one who got slain by the other sister, does anyone recall what happened to her knight husband??
