Well, damn.
I can see people getting annoyed with Adachi's thoughs and all, but it's so normal...
I have her age, and i can say that yes, it's extremely accurate. We really don't know what we're doing, every step is one or two questions without an answer. It's annoying, but it's not like we can change it, so try to actually look through things with her eyes at the end of the day, yes? empathy is a thing...
(Tbh, i'm not that indecisive and confused, but back there, when i realised that i liked girls, i was exactly like her so)
