Darlin'

Nayeon unconsciously hums a song.

"Since when do you hum songs?" Jeongyeon asks Nayeon.

"What are you talking about?" She replies.

"You were just humming."

"Are you sure? Sometimes when my brain really gets moving, it makes noise. I feel like I know this song by heart, but I can't pinpoint exactly what it is."

"It's just an earworm, Nabongs. It'll come to you in the blink of an eye." Jeongyeon rolls her eyes out of boredom.

"Okay. (Singing) Five little monkeys jumping on the bed. One fell off and bumped his head- Mama called the doctor and the doctor said-- No."

"Is this seriously what we're doing the rest of the night?" Jeongyeon complained.

"I'm surprised you have to ask." Nayeon continues singing.

The next day, Nayeon decides to call customer service.

"Hello, yes, I'm having an earworm problem and I was hoping if you can figure this song out. Daaaa, da, da, da, da, daaa, laaa. You honestly don't have any idea what this song is? Well, thank you, you're no help at all."

"So you have a song stuck in your head. It happens to everybody, Nayeon-unnie." Jihyo stated.

"Well, I'm not everybody. I have an eidetic memory and I should be able to remember what song this is, but I can't. Something's definitely wrong with me."

"This is the dreadful day that would come that I've been fearing long ago. This is my sign to descend into madness, where I cautiously test the limits of public nudity.

"Public nudity?" Jihyo questioned.

Jeongyeon walks in the apartment the exact moment Jihyo questions.

"Eh, that just means going barefoot." Jeongyeon chuckled.

Meanwhile...

Mina has second thoughts whether she'll call Quint, her supposed date that ruined their evening. The guy wouldn't spare a second to stop talking about himself not until they get to the point of talking about past relationships and Mina somehow mentioned Nayeon's name and that piqued Quint's interest.

And so, she chooses to dial his number for the sake of trying to get over the quirky, stubborn, but lovable Nayeon.

"Hi, Quint. Uhm, it's Mina."

"Oh, How are you?"

"Terrific. And I'm surprised to hear from you Mina. Given the fact how I acted the whole night on our last date."

"Well, we both made mistakes, you know. I took the last fry and dipped it with ketchup, you nattered over my ex-girlfriend like she was Leonard Nimoy and you were like my ex-girlfriend." Mina mumbled.

"So, to what do I owe the pleasure?"

"I was wondering if you'd like to get dinner again sometime."

"Yes, please. Let me just check my schedule." Quint eagerly said.

"This man's obviously trying to seem like a man with things on his schedule." Mina thought.

"How about Saturday?"

"Saturday works!"

Jeonghyo's apartment

"For the love of whoever's up there, Jihyo baby, Nayeon's been humming for the whole afternoon! Please do something before I get an ear stroke." Jeongyeon covers her face with a pillow to muffle her agony.
