@cosmicbangtan Are you even reading properly? She literally told Jooin and Jiho about this issue.
Similar to what the other users have said, the whole point of this arc is that Dani is bogged down by the opinions of those who aren’t close to her. She was literally “guilty before proven innocence” in their eyes.
I don’t get why people are so harsh on Dani as a character when her problems are legitimately hard to deal with. How much is ok when it comes to sharing the burden with your friends? What if this relationship doesn’t last and it’s not even due to anyone’s choices? Even if her friends trust her, what is she supposed to do dealing with outsiders who curse to her face?
Anyway, I don’t know about other countries’ education system but Dani goes to a gifted/academic school. From my personal exp, rumors from such schools can follow you everywhere you go even years after you left and everyone knows everyone lol, esp if they go on to top national universities.
