The story encompasses our protagonist, Nadia Vine... a girl who, on her debut day, regains memories of her past life and finds herself in a novel. The worst part is that she transmigrates into a secondary character who has been decapitated by the villain.
Both she and the character she's possessing have something in common: they are shy and fearful. So, before the true story begins, she needs to distance herself from the dreaded social scene of the capital. Thus, she ends up marrying a poor baron in the countryside.
However, he appears with a great delay, covered in blood? She ends up marrying the man who is the villain. All she can think is: 'I married the wrong person!'
Characters maybe I married the wrong person
Nadia Vine (main character of Maybe I married the wrong person)
She is a shy and fearful person, so she doesn't like to be the center of attention. She has a phobia of blood; if she sees it, she faints. When she’s surprised, she sneezes as a reflex...
She is loved by her parents. When they have an accident, Nadia is seriously injured, but her parents are not so lucky. They die right after her debut. This gave her uncle the opportunity to strip her of her family's wealth. To make things more interesting, he finds her a fiancé. A mercenary who earned the title of baron; the most serious case is that he is the villain who kills her in the original novel. Despite the fear it gives her, she tries to be responsible for his great mistake and will try to prevent her husband from killing her.

Altair Alesford
His first appearance was at his wedding covered in blood. A mercenary who earned his title of baron for his contribution to the war. He is an intimidating man, with only one facial expression (anger), so our protagonist always misunderstands him and thinks he wants to kill her. One thing is certain: he is shy when it comes to Nadia; he also sees her as completely opposite to himself, so he feels that he must protect her from the wind.
Her parents die in a fire at their home. While he was mourning, his family took advantage and kept stealing everything her parents left her. Leaving him with nothing but his clothes and an empty house. The land he owns is barren, so his lands are poor; he earns money by hunting magical beasts, which is very irregular income.

Blanc
Alesford's knight. He appears at the wedding (1st chapter) to temporarily replace Altair. He is one of Altair’s trusted knights. He always gives him love advice since he is popular among women.

Ana
The only maid of Alesford, she is very talkative and scatterbrained. She ends up being a great support for Nadia in the castle. Like our protagonist, she is weak against alcohol.

Cain
Alesford's knight; he is the third most chosen knight among the women of the state. He is charismatic and sings terribly, however, he manages to socialize with Nadia without any problems.

Pavel
Alesford’s butler, he is one of the most serious and efficient characters; he is loyal to Altair and Alesford. He has maintained the economic part of the lands. He has a very similar brother, Blanc, and also ends up giving Altair advice regarding Nadia, even though he doesn't know much about her.

Valhall
A relative of Altair; he is a cousin... he hates his Altair so much that he is waiting for his cousin to have no descendants so he can keep everything. However, he did not expect that despite all the rumors he spread, a woman would appear willing to marry Altair.

Opinion of Maybe I married the wrong person
Maybe I married the wrong person is a story that, despite having some clichés, is entertaining. The characters and their personalities are unique; you end up becoming fond of them. Its art isn't the best, but it’s not the worst either, and it compensates with its colorfulness and history.
The bad thing is that so far I appreciate the jumps in the story; at one moment the character is in a canoe and suddenly we are already past the point where she is drowning, and you end up confused and trying to give logic to what is happening... However, it’s not much, this story can become a diamond that just needs a little polishing so that it shines. It's possible that, like me, it will catch your attention.
