Noboru seems to have rotten luck at school when it comes to girls, because they all have eyes for only Yuuki – the resident Prince Charming. Tall, dark, rich and handsome Yuuki seems to be the exact opposite of the poor, short and not very manly, Noboru. Because Noboru is from a poor family, he had to work extra hard just to get into this prestigious Seihou Academy – which is mainly reserved for the rich and elites of the society. Before admittance, it was a dream of Noburo to hook up with one of the rich girls at Seihou Academy, but his plans seems to have gone awry, specially when all the girls seems to not pay him much attention and dotes on Yuuki the most. But for some reason, why does this drop-dead, gorgeous hunk, Yuuki, seem to want to get close to him?

For various reasons, Kota Kuramoto lives a plain life without TV, oblivious to fads and fashions as a completely out-of-touch high school student.

This comic puts a super star and a high school pauper side-by-side for a story of star-crossed love!
