Trying to find this manga!

Hi guys, I remember reading a manga a while back. It had a very stylized comic-like look, definitely not conventional art style. There was a scene where the two guys were in a cabin/shed on the school rooftop. Also one of the characters was very attractive to the rest of the school and may have been the club president or had a fan club? He was called the Prince of the school.
There was a very heartwarming scene where the prince confessed to his love interest with a bunch of roses? I'm not entirely sure, please help me find it!
