Thanks to the government’s romance encouragement policy, all high school students are casually enjoying love through a school-exclusive matching app. Amid this, Kuga Renji, who gets so nervous around girls that his whole body stiffens, has been branded with an F-rank on the app and is living days filled with despair. One day, by chance, Renji ends up helping the number one S-rank girl, Hoshinose Airi. In exchange for teaching Airi household chores, Renji begins receiving personal love lessons from her. With his inherent earnestness and eagerness to learn, Renji’s love power levels up in no time! As Airi watches Renji by his side, her own heart begins to soften… “I’m glad it was you who found out about my weakness.” A youthful romantic comedy about conquering love with an S-rank beauty!
