searching for this hetero manhwa

ight so there's this manhwa about a woman who was a commander in her previous life and she was considered a massive asshole, no emotions blah blah blah. She gets killed and then is reincarnated into this medieval fantasy world, she looks like a dude, but yes she meets a prince (black hair) with twins (red hair) as advisors. She becomes a squad leader and gets sent on a mission where she gets...kidnapped? adopted? by this (long light blue haired) magician who is initially considered an antagonist in the story. But then I think the magician is starting to fall for her,,,

I do be hoping this rings some bells for anyone I'm pretty sure it's a popular manhwa,,I just cannot seem to find it ANYWHERE.
