It all starts when Marisa picks up the wrong cell phone. When she goes to return it, she feels something she's never felt before, something a bit like...love. But Marisa and Rene aren't exactly a match made in heaven. For one thing, Marisa is a "chola," and she isn't petite; she's a lot of girl, and she's not ashamed of it. Skinny Rene, however, gangles like a sackful of elbows and wears a calculator on his belt. In other words, he's a geek. So why can't Marisa stay away from him?
