Hello

Looking for this romantic manga, between a "deliquent" and a "nerd". Although, in reality is quite different than how they looks. The guy skips school, acts real tough but doesn't know how to fight, i think he also quite smart. The nerd has pigtails wheres glasses and everyone believes that she is really intelligent but in reality she doesn't get good grades, in fights she's stronger than the guy. I think she used to be a delinquent in middle school, i don't remember but she did a complete image change in high school. Well she used to bother the main char a lot, follow him around to get him to go to class (I think) and sometimes she follows him in the bathroom. This is where my memory ends, last time i read this was about (3-5 years ago), and i curious to find this again and read. When i last read it the manga was ongoing to i am hopping it is completed now... Or like most of the good manga out their it could have been dropped lol But i do hope someone recognizes this <3 Any help is appreciated.
