I think this kind of book really suit Sigrid. Basically, she do not care what the prince doing as long as he is safe.Everyone: "This job will be terrible and humiliating."
Sigrid: "I don't see the problem. I just have to follow him and not get hit."
I would say in her defense, she's uninterested in love tbh. She's more focused about spending time with friends and honing her skills as a knight than looking for love. She does say in earlier chapters that she doesn't intend to start a family. At least not at the current time.The bratty third prince would break first. No doubt about it. Unless something beyond Sigrid's control happened, she would continue to protect him and the third prince would start to mellow out.
Also, Morris is back. And what's this? Veramude is there as well. Oh man, there would be a battle between the two potential love interests. Meanwhile, Sigrid is dense & oblivious to all of it.
