"There's something on your face" Bo gum pointed out timidly, helplessly trying to hide his smile.

"What is it?" Irene asked innocently, tilting her head to the side.

"My gaze" Bo gum replied and turned red as a tomato; in embarrassment and she burst into a fit of laughter.

Irene has to replace her best friend, Wendy as a babysitter when she has to go somewhere else. Irene has no experience with kids but she's willing to help out her friend. What innocent Irene doesn't know that the five year old kid she's supposed to be babysitting has a very hot (And not to mention, kind hearted) older brother, named Bo Gum.

What happens when the two pure and innocent souls come face to face with each other.

Can Bo Gum and Irene keep their throbbing hearts in control?
