Mischievous Kiss

In their high school years, it was funny and cute. But proceeding onto their college years, you would think the female lead would mature. But instead, she was still a whinny, crying and a bit too clingy girl. Whilst the male lead was always trying to make her study or become a better person, it seems like her priority was to interfere in every aspect of the male lead life. I think it would've been a better plot line if she became independent, better herself and learned to be a better person. Then the male lead would've realized what a true gem she was.
