Please help me find this story!!!!!!

Okay so I read this close to seven years ago on WEBTOON and haven’t been able to find it since the WEBTOON purge.
The story focused on a mysterious main character who was I think a freshmen or sophomore in high school now in this school everyone has wings that come out of their arms but they can’t fly until their junior year I think because of age reasons. They can’t fly until contract the wings and make them normal human arms and they get trained on how to use their wings before they take flight. The main character he refused flying practice and avoided everyone in his class making him the loner odd one out that no one understood. At some point some upper class man pisses off the main character stealing his stuff and flying off with his other friends and while some people are looking at the main character with potty he pays them no mind and starts flying like no one’s business. Just so happens he’s stronger more controlled and faster than the upper class men and is then revered as the freak of the school and some investigation starts where they try and figure out how he knows how to fly and how old he really is if he did lie about his age and there were some other complications in there but that’s about where I last remember the story being.
I think there was a romantic interest who was a girl that took part in being super suspicious of the main character and joining up with the investigation team to find out more about him but that’s about it for the romance I remember.
