[5] The series aired on SBS TV at 22:00 (KST) from June 19 to August 8, 2020, on Fridays and Saturdays for 16 episodes.

[6][7] After being dumped by his girlfriend, Dae-hyun (Ji Chang-wook) is approached by high-school tough girl Saet-byul (Kim You-Jung) who needs an adult to help her buy cigarettes, but she is rewarded with candy and a lecture instead.

Although high school girls like to come in and take pictures with him, the store doesn't make a lot of money.

In order to keep his business afloat, Dae-hyun's father urges him to hire a part-timer to help him out with the store.

Dae-hyun has been suffering due to his convenience store not making enough money and his unreliable family not helping enough.

While trying to make his business successful, Dae-hyun seeks to advance his relationship with Yeon-joo; there has been interference due to mistrust and insecurity.

Yeon-joo has heard gossip about Dae-hyun hiring a beautiful part-timer, but isn’t concerned until they meet.

Saet-byul feels she has inconvenienced the Choi family enough and moves out, but she has trouble finding a stable job and a place to stay.

Her friends can only give her temporary shelter due to detractors seeing her as a problem; Dae-hyun's mom convinces her to stay with them for the time being.

Seeing how she never completed her high school education, Dae-hyun helps Saet-byul in her GED studies.

Yeon-joo discovers the reason why Dae-hyun left GS Corporate was because Seung-joon encouraged him to take the fall.

The delinquent trio intend to visit Saet-byul at the store for money, but they get scared when they see the police talking to her.

Their reputations are now tarnished; Eun-byul is forced to leave Fancy Girls and the locals fear Saet-byul.

However, he collapses due to exhaustion; HQ sends employees to help him manage the store while he's away, but the new staff doesn't get along with Saet-byul as Yeon-joo wants to get rid of her.

Yeon-joo can sense the romantic development between the two and starts forming better relations with Dae-hyun's mom as a counter.

Disappointed that he would squander such a chance, Saet-byul feels guilty that mother and son would fight over the matter.
