It's interesting when people are drawn to people who are bad for them. Myself included! I dated a guy who was a lot like Park (except not ambitious, so even worse lol). There was a kernel of something that seemed good and essential at the time, but also some toxic things and incompatibilities.
I had to see for myself that being with him made me feel and act like a weaker person, and good relationships don't do that.

My university was in the midwest, also rural. If you came back to the dorm after midnight, you all had to check in with your ID. It was only about underage drinking, not preventing fellow students from staying the night.

On first read, her anger seemed unearned to me- like she should've seen that he wasn't serious about her like Hanna did and we did as readers.
But now I think that there's a tendency for people tell themselves a story of what the relationship is. Even more so in a long distance one.
