Alicia is a commoner granted a scholarship in a prestigious academy, where even a prince will become her classmate.
She is the only person who can use light magic, and is meant to help the nation to subdue the Demon King in the future.
She quickly proves to be all sweetness while meeting the three smartest and hottest boys in school.
This is meant to be the plot of an otome game, however, Yumiella becomes aware at a young age that she played the game in her previous life.
Somehow, she is immersed in the game, and knows her character is meant to become a trouble in the future. However, she was not exactly fond of playing the dating sim, instead, she was a true gamer, competitive, aspiring to level up as soon as possible.
With the same spirit, Yumiella decides to avoid disaster and starts to build her strength immediately. Now, she is meant to enter the academy, and accordingly to her father, find a prospect to marry.
Yumiella has other plans and doesn’t really care what his parents think, after all, she has never had a relationship with them.
In the meantime, Alicia starts to build a trusting relationship with Prince Edwin, Oswald and William, those meant to help the game protagonist to defeat Yumiella.
On the entrance ceremony, Yumiella meets Alicia for the first time and decides to stay away from her and her escorts as much as possible.
Unfortunately for her, she forgets that new students must test their magical powers in front of everyone. Yumiella spent a lot of time fighting all kinds of monsters on her own, and she realizes that she doesn’t know what her level is.
Alicia is, as expected, a rookie with the lowest ranking, William has trained his entire life for this moment and surprises by reaching level 10, but once Yumiella appears as a level 99 mage, problems begin for her.
For now, one thing is certain, Prince Edwin cannot believe Yumiella and accuses her of being a cheater.
