@Sad_Reality Would have been too simple. Plus she is a superiority complex, a big ego and lot pf pride, she just don't want to say it's her because it will hurt her image but that's obvisouly backfire.
The funny thing in the chapter is how our MC is happy when she think it's Ai-chan who bully her because that mean she still think of herand it's shocked to learn it's not her.
@JustReadingShit We're more than a potential suicide here. I think Ai-chan rather die than admitting the truth.
