Forgot the names of 2 manga/manwha

[Mogel]

I've been trying for a while to remember the names of two stories I read during a binge a while ago. I honestly cant even remember if they were manga or manwha. I hope the bit off them I remember could help anyone else find out what they are:

1. Female MC ends up crossdressing in a fantasy world were she pretends to be a great sorcerer/engineer in order to win over the lord of a western fantasy castle.

For this one all I remember is what happened in the last chapter I read

2. Female MC meets a young girl who was supposed to marry the emperor, however the FeMC finds out that the girl is autistic and then they bond over cooking. (I believe the girl has a silver haired brother)

I thought it was that one at first as well but the story I think I remember was an isekai where the FeMC introduces modern tech, specifically weapons to win over the Male MC.

OK I FOUND THE FIRST ONE
It is I Will Go with the Emperor's Ending https://www.mangaupdates.com/series.html?id=157437

Still trying to find the second one but I think remembered some additional details:
I believe it's one of those stories where the FeMC goes to information brokers in order to find a contractual husband in order to help herself and she ends up with the male MC who is the secret leader of the info brokers.

Remembering the stuff I read seems to get easier when I'm not trying to do it while tossing and turning at 3AM 😅
