Hiii i was also wondering how do find the hairpin and another thing is that i tried 5 times already to get with thane but its so hard... TwT helpEDIT: after 2 more tries i did it NVM!
Just so you know, The hairpin is to go into the principal office and touch the globe, and later ask about sirens to get the diary/true ending
It has nothing to do with Thane’s route. That’s more about finishing finding the culprit quest. Hope that helps
