To recall, Chief Hong rushed to Hye Jin's dental clinic out of worry and helped in arresting the patient who caused a huge disturbance.

Because of this, Hye Jin saw that it was just polite to thank the kindhearted Hong Doo Sik personally, and even gave him wine.

The two then ate dinner together at Doo Sik's humble home, and drank the wine she brought. The next day, Hye Jin woke up with a severe headache next to a sleeping Doo Sik. To her shock, she immediately collected her things and went straight home. But even with her careful and vigilant steps, she wasn't free from the community's prying eyes.

As soon as she got home, she was welcomed by her best friend and dental assistant, Pyo Mi Seon (Gong Min Jeung), with a message in a chat room where Hye Jin and Doo Sik are the topic. In addition to her despair, she doesn't even remember what happened last night.

With her messed up mind and hangover as well as Gongjin's gossiping mouths, she bravely marched to her clinic. However, the face she dreads to see was the first one to welcome her day. When Doo Sik asked the dentist to breakfast and cure their hangover, the residents of Gongjin, led by Jo Nam Sook (Cha Chung Hwa), played as spies and watched the two eat together.

This made the dentist extremely uncomfortable, meanwhile, Hong Doo Sik kept his cool. After eating, Hye Jin lost her temper and confronted Doo Sik.

The kind man who is always there to help everyone, even Hye Jin, was deeply hurt by Hye Jin's words.

Although she didn't mean it, Hye Jin delivered her words tactlessly, implying that she will never fall for the man due to their societal differences and contrasting lifestyles.

Her embarrassment amplified when police officer Choi Eun Chul (Kang Hyung Seok) dropped by to buy dental floss, who happened to be Yoon Dental Clinic's patient and the apple of Mi Seon's eyes.

With her brazen personality taking over her, she asked the police officer what his ideal type of woman was. At home, Mi Seon spent her day off watching sageuk or historical dramas after the charming police officer said he prefers women who look good in hanbok.

Since Hye Jin's dental assistant, Mi Seon, is currently under the weather, she called for the all-rounder Chief Hong, who immediately came to the rescue.

Hye Jin's neighbor, Choi Hui, who happened to be a teacher in Gongjin Elementary School came to her house to formally introduce herself. The two found out that they will be seeing each other in school for Hye Jin's dental education session for the children. In the homeroom classroom, Hye Jin and Doo Sik danced and sang together to the song that teaches the students how to properly brush their teeth.

As a payment for his exemplary help, Hye Jin treated Doo Sik to lunch in Gongjin's neighboring town to avoid being Gongjin's gossiping victims.

In the restaurant, the two shared a moment which was far from their usual bickering selves. Hye Jin and Doo Sik actually spent their lunch with a light heart and an exchange of warm smiles. The dentist also found out that Doo Sik is an engineering graduate at Seoul National University, one of the most prestigious schools in South Korea, which made her feel bad for judging his character and apologized.

Before the food was served, the two spent their time solving CSAT mathematical problems on the table, which drove the restaurant owner crazy. Hye Jin is a woman of principles, who likes to play by the rules.

On the other hand, Doo Sik encourages Hye Jin to live a little, and opens her eyes that there is more to life than stressing out over money and success. These kind words softened the dentist's heart, even agreeing to Doo Sik's abrupt decision to run and play at the beach even though the sky was pouring huge amounts of rain.

Hye Jin and Doo Sik, without a doubt, spent their day well with each other's company. After they played in the rain, Hye Jin worried about herself getting sick, and like a knee-jerk reaction, Doo Sik quickly checked her temperature.

The sudden skin-to-skin physical contact made the dentist blush and remembered what really happened the other night. In her memory, the two of them shared a romantic, passionate kiss.

However, Doo Sik, in a heartbeat, denies it all and firmly believes that nothing strange happened between the two of them.

At the end of the video, it was revealed that Doo Sik experiences nightmares for years, which gives him extreme difficulties in sleeping.
