Maybe because she wants to try to piece together her own foggy memories bc she feels incomplete without the whole of the memory that's been haunting her since forever
Yeah that maybe the case but one should live in present as being so obsessed with your past can ruin your present.
I don't think it's as simple as that. I mean, think about it, this even traumatized her sm that she can't stand the sight of spiders despite being pretty fearless otherwise, and clearly the "spider" she saw was something much more sinister (maybe a corpse?). And the worst part is that she doesnt even know what exactly happened in this important memory. Trust me, it isn't easy to just ignore what happened in the past and move on forward (perhaps she'll develop into someone who will let go of the pas and just live in the present as the manhwa progresses tho) bc you'd feel like you literally are missing a part of yourself. Ofc i'm not saying that what you're saying is wrong (bc it really isn't), i'm just saying that it's easier to tell others to forget their past than to actually do it yourself
But it's kind of pissing me off so much that miss is so fixated on her past and ignoring the yungjoon just why can't she let go of her past painful memories and live happily in present.
