The private school, Cross School that Ryoko attends, is a special school that has an art faculty. However, Ryoko does not have any interest in people from the art faculty! Unlucky for her, the well known [Prince of the Art Faculty], Sei, stole her first kiss <33 Furthermore Sei keeps clinging to her without a reason, causing her to get excited. But Sei is younger than her, has a huge ego, and is super perverted! Oh my gosh~!! Ryoko, what is gonna happen now!?!?
