What does you being a twin matter? You don’t like the story you don’t like the story end of discussion
I aint a twin but I think it somehow relates to her inner secret frustrations maybe.. I think siblings feel jealous w eo and twins facing jealousy might be more common specially if it's even identical twin
Imagine u like a guy but that guy likes ur twin at first, u might feel an emotion which u cant even express.. then the guy anyhow starts liking u /slowly developed, ur mind will constantly churn to think "is he liking me cuz he liked my twin in the past" "am I the substitute" etc etc it'd just one example.. which anyone can face not only twins but the probability iin twins gets more common.
The past that was w ur twin is now attached to u. I, who aint even have a twin always grtd oissed off over tropes like this so her belonging from that side might anger her even more uk.. (can be other reason also tho)
I fucking HATE this story, everything is buns, the ml is a piece of shit and I have EVERY right to hate this shit especially because I'm a TWIN and this story is fucking trash.
