autist here, i found myself largely relating to lee, of obsessing over a person and wanting to know everything about them, to be there for them, to know their history n stuff. But if the person tells me to just stop, I stop stalking and obsessing over them, but they occasionally pop into my mind but i'm able to rid of it quickly. I dunno if its the same for everyone but you just kind of respect / like them too much to disregard their opinion and want.
