Maybe it's just me but I don't think MC intended to stalk Maron. I just realized that almost everything is written/drawn from her perspective of view. And to get information for the readers, she more or less has to be following her, or else we only get to see what MC sees herself. In a way it's stalking, in another way it's just the perspective of view.
But I don't know, that's how I see it.
It's how I see it as well: she's a baby lesbian in baby love taking baby steps towards her goal, which she isn't even all that certain about, but whatevah, she pluckily perseveres!
(That oil tycoon fantasy where she buys Maron 24/7 forever is the closest thing to a goal she has figured yet, lmao!)
