I was worried something bad happened between Catherine and Henry, but it just turns out to be a budding romance lol
It's nice the story is continuing past the "original story" by the author. Also, the girl aiming for Killeon rushed too much and has definitely made a big mistake - the guy from Hamad definitely knows Henry somehow, and I seriously doubt this could in any way be framed as an affair.
I hope the guy was not actually looking at Edith but at her knight and maybe recognized him from somewhere? Either way, I hope that relentless bitch's ploy fails, just let them live in peace ffs.
This is giving off a "I think your knight is really a missing prince / child of a high ranking nobleman, but I wanted to let you know in private." vibe.
