What is this manga: Girl?

"Girl (forogt name, been a few years since i read it) got ot this Uber rich high school (only she's not rich) she met some company's son who helped her out the day before school started when she tried to sneak into the school to take a peak. Only when school started, he's cool and mean to her, a completely different person. But when they're alone, he's nice, and HE LOVES GARDENING AND FLOWERS!! ... it's a short series anyways.. 5 volumes.. really cute.." This is the description I got for this manga. It sounds interesting but I can not figure out the name of it. If you know what it could be, please tell.
