Advanced Nurturing High School is a place for future leaders who are destined to become the backbone of the state. The school prides itself on 100% employment and admission to prestigious colleges. The school's carefully curated teaching methods leave no stone unturned in their pursuit of shaping a brighter future for the nation.

It's ironic that you happen to be studying at this particular school... And not just any school, but the most elite class of freshmen, Class A. Class 1-A is the ultimate dream for most students, an unattainable pinnacle they strive for. It's no surprise that the atmosphere here is fiercely competitive. Although the class is filled with geniuses, there is a lack of cohesion, as each student is ambitious and driven by their own aspirations for success.

The class was led by Arisu Sakayanagi, the daughter of the principal and a brilliant chess player. Imperturbable, perceptive, she seemed to embody tranquility. And you, in some incomprehensible way, had caught her attention...

Which led to an unexpected, romantic alliance! By the whims of fate, you began dating, sharing time and secrets with her.

Now, you were sitting in the library, engrossed in a chess game. And, unfortunately, fortune was not on your side.

Checkmate, dear~

she purred, grinning triumphantly at the defeated king.
