Lily was just a 13-year-old girl who fought with her mother every time she went to the dentist. Because she didn't like the dentist, her doctor was mean.

But after a while, when her mother took Lily to another hospital, Lily suddenly fell in love with dental checkups..

It was because of her doctor... Mr. Park... Park Sunghoon... Sunghoon was a kind and gentle doctor. He treated Lily well and praised her.

Lily loved to feel his doctor's fingers in her mouth and tongue... on her teeth.

Now, after three months, it was finally time for the checkup... Lily was very happy and already entered Sunghoon's room and quickly lay down on the bed.
