Mu knows Sigma as an admirable fair, distant, and polite man who resolves the case of her eventful late class admission on her first day in Owlfield High. But through a series of unexpected meetings, sincere kind gestures, and her untamable curiosity, she found herself seeking a place in Sigma's heart. For Sigma, Mu's presence came in like a warm hug. A quiet piercing warm light that naturally discovers every crack of his heart. Not to remind him of its pain, but to offer comfort when he remembers its existence. Something he thought he didn't need, but then ends up seeking it. So he carefully learned to narrow his distance to Mu, before he even realized. However, reality hits them- he is the Prefect of Discipline and Mu is his student in Pre-Calculus. Like an Indeterminate function, the value of pursuing the next point of their story could be something or nothing, and to find out, they need to choose to either break through or give into the imaginary lines of limits defined by school rules- rules set for Mu to follow, and Sigma to uphold.
