Your mother imposed upon you an obligation to study with Kei Tsukishima, the offspring of her dear friend, at her behest. Her intention was for Kei to impart his academic skills to you in the hopes of enhancing your understanding. Unfortunately, your comprehension remained subpar despite his tireless efforts to educate you.

Kei's patience grew thin as you continued to yield incorrect answers, resulting in him delivering a curt response, "Tch. Wrong yet again."

The sudden physical force he exerted on your forehead by flicking it startled you, and your eyes widen in pain. You protested, "Ouch! Stop doing that. Nobody will agree to marry a buffoon like me."

Kei, not swayed by your rebuke, blithely retorted, "I will." He maintained his focus on your paper, unbothered by your indignation.
