xylene's Manga

[at ch26]
It was quite good and funny at the beginning, but as I continued I started to feel like "why our mc is so stupid?". Like even fot her, who was 27 before she got reincarnated has a hard time to deal with her brothers? I know she feels bad if she made them sad. But like DUHHH I just hates it when someone's hurt and will always try to hide, like- what's the point of hiding? It won't kill to communicate. Eventhough she lived for 27 years theres nothing she learned? Atleast some basic work she'll knows right? Or does she like just spent her life getting bullied by them? (Or is it that I've seen to much smart mc who would take advantage of being reincarnated, ands knows what to do for their advantage?
