The Male lead A.K.A the "Hero" is a yandere creep of a stalker who quite literally forces the marriage onto the Female lead.
Aria after hearing what she can about the "Hero" almost immediately go's to try and quit her job and leave the country, but is stopped by one of the "Heroes" party members as soon as she tells the Princess of her plans.
Which also irks me a bit by the way, EVERYONE is working together to get Aria to accept his proposal (Except maybe 1-2 people who are never heard in their rejections).
I mean he literally puts a device on her wrist in the form of a Marriage bracelet that not only ties their lives together (yea if one dies so does the other...), it also has a magnetic effect pulling them together.
The "Hero" seems to force anyone getting between his getting married to her with force.
Not to mention I saw one of the later volume covers showing Aria being held in the "Heroes" arms while smiling..... yeaaaaaa not likely.
Her only skill lets her view things in a realistic manner as well as be blunt with her opinions on things around her.
The only way that cover will be true is if she is brainwashed or he saved her life or something from let's say a demon out for revenge against the hero.
But even that would probably not happen since all the past stuff would be such a turn off for a relationship that any woman except one that is really into having other decide their every life function.
I have to say I wasn't expecting to be so creeped out by the "Heroes" many actions...
I won't rant anymore about the bad stuff I guess, but let me tell you there are at least 5-10 more things I want to post in this but am too tired to do so.....
