Description-
A fiancee was decided for Jared Murphy (16 years old) who was the eldest son of a baron family but couldn’t succeed his family. The other party was Olivier Alway, a duke’s daughter (26 years old). Olivier who everyone talked about being a beautiful woman, was famous for her bad personality and vulgar mouth. Moreover, she was ten years older.

Jared’s small ambition, which was to become an adventurer to say good-bye to the aristocracy society, had ended when he was informed of that, at the same time, the court magician’s path that everyone yearn for had opened for him.

As he overcame factional disputes, discords between magicians and knights, magical beasts exterminations, and conflicts with secret organizations in dramatic fashion, he became aware of the true appearance of his fiance Olivier and got to know her better.

And then, he would meet students, knights, magicians, and heroines of nobility ladies from the same school.
The student magician became the fiance of a duke’s daughter and rose up to become a court magician.

Thoughts-
Our protagonist is Jared Murphy the eldest son of a baron with a status as a talented and rising mage whose dream is to be a well off adventurer away from the troubles of Noble life. Unfortunately he has been forced into a marriage with a Duke's daughter Olivier Alway is not only 10 years older and is also having bad rumors surrounding her alongside her terrible attitude. How's Jared's life go on from now?
There is a teaser at ch4 for a future conspiracy surrounding his mother
Also I haven't read raws and there are two translators on this project but I prefer daikyuntls work more than kuhaku light novel translation since the latter's site has some forced ad notification you can't delete on mobile.

 

the novel title is overwhelmingly long!!
japanese novels titles are not getting any better at all...

 

Ikr

 

It's like the title itself told the whole story plot without spoiler tag!

 

Well it got picked up again
From right I know it's mc then Olivier and then trene who are the other two?

 

My guess is maybe some student girl and some noblewoman

 

Ah I meant if someone could translate the names

 

Ahh okay, I'll maybe try later. Started Japanese, so I've been wanting to practice a bit.
