The hell? How do you act like your 26? Do you mean, because she‘s 26 she has to act mature? Dude, not everyone in their 20s is mature in this world.
first of all, she doesnt believe she's the heroine, therefore she has no reason to believe they will target her. therefore she has no reason to be that anxious and easily swept away by the mls. second, the author intentionally added in the story that she's 26 yo, so that should at least have some relevance to her worldview and how she acts around the mls and in the hs setting. she doesnt need to be "mature" but there should at least be a noticeable difference in her behavior compared to the students, but there is none. for example, in her second chance at life, she wants to be academically studious, yet this doesn't have an impact on the story.
She doesnt believe she is the heroine because in the story that she wrote the heroine comes later in the story, and just because she wants to be academically studious doesnt mean she has to act her age because she can still be academically studious even if she acts like that. Everyone has their own personalities. Why does there have to be a “noticeable difference in her bahaviour” than the students? She still has the right to act how she wants and i know you didnt say she doesnt have the right but still. I hope you dont think of it as starting a fight because i really am not. If this doesnt make sense im very sorry as English isnt my first language.
to clarify, since she doesnt believe she is the heroine, she has no reason to be worried the mls will obsess over her, therefore she should be able to reject the mls firmly instead of just going along with their whims. since she wants to redo her education, it should show up in the story going forward (ie. show her actively studying or making plans about it. in fact the story could've shown her trying to study but getting interrupted by the mls. it would've still gotten the point across that the mls are unpredictable yet shows the relevance of her age and real-life circumstances). but so far, it had been meandering slice-of-life interactions with the mls. i dont think she necessarily need to act like a 26 yo, and she can have whatever personality she likes, but if it is going to be mentioned, i expect it to have some relevance to how she acts compared to the hs students around her. yet it doesnt; she acts like the typical bland self-insert and i find no difference to how a college student would act in her place. and tbh arguing over her behavior is pointless, bc it's clear the story's writing is just bad.
girl ur 26. act like it
