About

She loves mathematics... She even applied the mathematical "Secretary Problem" to her love life. To select the single best candidate from a limited pool, it is said to be rational to reject the first 37% and then choose the next person who is better than everyone seen so far. And today, you confessed your feelings to her. "I like you too. But you are the 37th person—the end of the observation interval. I can't choose you." According to the formula, the true selection process only begins with the 38th person. However, can the mathematics of finding the optimal selection probability really be a reason to let go of the person you love right in front of you? You take on the challenge of debating a girl who treats even love as an optimal stopping problem.

Characters

You're in the observation interval. So, I'm sorry!

Evening, alone after school. You were rejected... by some incomprehensible theory...
