the last day of summer

Marilla knows, Diana knows, Bash knows, everybody else knows. So why can't the two smartest kids in class figure out this complicated equation called love...? (A shirbert fanfic, BASED IN 2018) please read before you start the story so you aren't confused: this takes place after the events of season 1 and 2, so it's basically like "season 3" shirbert but in modern time! :) Also there will be *flashbacks* from the other seasons but modernized. Also this takes place 1 year later from season 2. (So Anne is 15 and Gilbert is 17)
