The ML is really annoying. Basically the problem is: 1) he's immediately super duper into her and super doting and protective but 2) he's supposed to be the commander of a knight order and her main boss.
These things do not go well together.
I stopped reading when MC got a cool mission and ML was being a huge wet blanket at pretty much every stage. She gets called to talk to a super important person and he insists on tagging along because he's worried

During the meeting he keeps interjecting when important person tries to tell MC important stuff because that's supposed to be top secret

( Important person wants MC to escort them somewhere and ML insists on tagging along because if MC went alone and something went wrong MC would get in trouble

(( MC is getting some important exposition from someone and ML interrupts because that someone is a dude and he's jealous
