An AU in which Rui is a Prince and Tsukasa is a skilled pianist and entertainer for their palace. However, considering the King & Queens fondness of Tsukasa, they can't give him a break! And poor Tsukasa has to overwork himself with finding ways to please the Royal Family, which Prince Rui slowly realised and grew concerned for him despite his usual carefree personality. Of course, Rui contained those emotions away from his parents.
When the upcoming ball reached Tsukasa's ears, he knew he'd have to work harder to please not only the King & Queen, but all the visitors at the ball. Sleepless nights will occur, and he knows it. Though, Rui found the ball an idea to minimize Tsukasa's work instead of giving him more.
Who would've known that the ball would fall on Tsukasa's on birthday!
And who would've known that he was about to receive the best gift of his life...
