(By: weilanran on insta) Pantalone is a Professor, As you pick the course Engineering... The hardest subject is "Calculus". This has so many solutions and explainable things how to solve. Your grades are perfect and so are the other subjects. Timeskip, After class, you're ready to leave the classroom not until someone calls your name and you realized the classroom is now empty... You and Pantalone are alone... He was right there...
