From Aerandria Scans:
Takatou Mitsuki luckily passed the exam for Honmaru, an elite high school, and now she finds herself struggling to catch up with all the smart students here. To make matters worse, Mitsuki was chosen as her class’ representative in the Survival game at school. Amidst the chaos, she finds out that Honmaru has a system where scholarship students are expected to take care of students with poor academic ability like her. And thus, Mitsuki is stuck with this handsome guy called Aoi Kousuke, who’s only helping her because of the money he gets from the school. But somehow, Mitsuki has the feeling she has seen Aoi somewhere before...
