in the next chapter...he will apologize for coming so suddenly(he wants to check her hand and see if it's injured or not because for a moment he saw her and he wants to confirm it.) then they start talking and she says that she needs fresh air and he says he will accompany her to go and walk around some place(forgot the name) and when she stands, her head gets dizzy and she is about to fall and he holds her so he sees her injured hand so the cat is out of the bag^^

in the past she actually killed his brother tho? she would get killed by his hands either way in the past but the king ordered her to kill and that was carefully thought out i suppose, i'm sure the king wanted to get rid of her either way so he planned this like that and except for the king and his daughter no one knew her identity so he couldn't have figured that out that easily but well...he killed him by herself and war or not she would've been his enemy and he would've killed her either way.
but believe me...this man is so smart and persistent. at least until chapter 20 lol.

The ML has the king's daughter next to him in those scenes of the original timeline . If anything the FL, the King, and the King's daughter should all be killed. Not just the FL. It doesn't track that an group of assassins just killed his brother on their own. Was he not concerned about who hired the assassins?
Of course we will never know, but it is all a bit too convenient.

she was framed since the beginning yes...they saw a killer and they executed her..just like that. if the ML did other researches on the king and his daughter after she was killed or not...we can't know about that now, can we? we just know she died bc of her following the order of that asshole king to her own death.
she is caught...let me tell you that this man(male lead) is veeeeeeeeeryyyyyyyy sharp from what i saw in the raws and he doesn't back away...like no way in hell...
