These sisters in this trope are always so delulu it’s not cute

Right? This time the younger sister thinks MC robbed her of their parents live apparently (though I doubt it's actually like this) and because MC is a better student she is "taking over the school"? Or is the problem that she talked once with an hot guy? Is that taking over the school? I'm so confused by their reasoning

EXACTLY.These ‘reasons’ are getting out of hand now , nothing makes senseI’m a bit tired of this trope (but ofc I’ll read it)
