Kouta is the school's idol loved by all - his teacher, and his fellow students. At least the one teacher and three students we see. Who are all girls. And they don't actually "love" him all that much, they just want to fuck his brains out.
A pop idol has a friend. This friend has a crush on the pop idol. A second chick has a crush on this friend. To spice things up further, the pop idol's manager has a keen interest in her and might force her to do things she doesn't exactly like. Or does she?
