From Tokyopop:

In a private school only recently open to girls, flower-lovin' Takaaki is a breath of fresh (and gender-blurred) air! Having to room with the stone cold Sonoh Takahara has certainly caused him some angst, but don't fear. Sonoh's twin is his complete opposite, making for a whole mess of fun filled with cute boys and silly misunderstandings.

Yuki Tachibana, a withdrawn third grader, is convinced that the fourth floor of his school is home to supernatural creatures that few kids (and no adults) can see and he's worried about a recent influx of new, less friendly creatures and about his ability to perceive the true shape of things waning as he gets older. Most of the other kids mock Yuki - they think he's crazy due to his strange pronouncements and peculiar actions - and, aside from the creatures he sees, his only social interactions are with the school's kindly and open-minded caretaker, a new transfer student named Makoto Suzuki who's allocated the desk next to his and an enigmatic boy named IQ who always wears a box over his head.

Suppose you were so beautiful that people mistook you for a superstar, a model. So beautiful that strangers went out of their way to catch a glimpse of you and shopkeepers offered you things freely. Kyung-hee Goh is that girl. Trapped by the feelings she evokes in other people, she steers through life alone. Boys are either too intimidated to approach her or think she should reward their compliments with her attention. Then she catches the attention of the baddest boy in the school. And that's when the battle really starts...
