A young girl, Mahiru, is really tired of life with her parents, so she decides to move away after leaving them a notes. She has really nowhere to go except for her childhood friend and so... the adventure begins! First she must learn how to acept his job as a male host (men who work in certain restaurants to make women feel happy and wanted as they buy lots of expensive drinks and food--sex not included), and then one day, they find a little baby on their doorstep!
Mahiru and the baby don't like each other, though they will unite forces if there is some woman claiming his attention... And in any case, whose is the baby? Can it be his...?!
