GOOD GOOD SHES NOT IN LOVE WITH ISAAC
I always thought of them as just having a brother and sister relationship. And she just acts all blushy and shy in front of him is cuz she isn't used to it yet and just likes how he acknowledges her efforts in being a better person.
Unfortunately after I read 20.4 she apparently is. And I really hope that it doesn’t imply he feels the same.
