Hi all, I remember reading this years ago and wanted to read it again but I can't seem to find it.

The premise was a prince was dressed up as his sister and secretly got married off or sent to marry another prince to create good ties with another nation or something like that.

I remember that the prince was immediately found out to be a fake by his fiancé but he still went along with it and didn't out him. The fiance was also bad tempered.
I remember a scene where they embroidered with the other ladies and he might have been posioned?
I know there isn't a lot to go one by here but I have it stuck in my head and for the life of me I cant find it anywhere.

Thanks guys

Maybe Lala no Kekkon

Maybe Kiss Me Princess? Im hoping that's it, I kinda wanna read the one youre looking for too.

How did you find it so quickly, I've been searching for weeks!!! That was it! Thank you for your help! 🙂
