Even though it's a comedy, this can be a serious issue. Imagine, being the top of your class and everyone looks up to you. When you do well and even excel, everyone just assumes "as expected of her." They think everything you do is perfect, so you don't need praise for your efforts.
Getting to the top requires a lot of work and sleepless nights. So, I can see why Senpai might crave that kind of attention. Plus, I like girls, who seem to have it together, but are secretly needy.
