Seulgi and Irene sat on a coffee shop, only few blocks away from Pusan University. They're sitting beside a huge glass window, they can clearly see the people going in and outside the shop.

Seulgi placed her arms on Irene's shoulders "Ahhh, they're both so slow"

-- "Yongsun said she's around the area" Irene replied as she looks at the time

"Well, attorney is a bit busy these days" 

-- "How did you know?" Irene replied, raising an eyebrow

"Of course Byul told me" Seulgi replied in defense

-- "Let's order for everyone, I'm hungy!" Irene uttered as she sigh

Not even a minute, they heard Yongsun entered the coffee shop, panting, holding a book in her right hand as she walks her way to their table

"Wow, Kim Yongsun. Busy?" Irene greeted her

-- "A bit" she replied, she sighed as she propped herself in her seat

"Only you? Where's Byul?"

-- "She said she needs to ask her professors for recommendation regarding her thesis, her topic has been rejected many times, she's really struggling. She won't ditch us, don't worry" 

"Unnie you looked tired, Rene already ordered some food for us"

-- "I'm fine"

They noticed that more people are coming inside, it's raining

"Byul didn't brought an umbrella with her, wait, I think I need to pick her up"

-- "Unnie relax! Stop treating Byul like your kid, she's your girlfriend unnie. Stop worrying too much, I'm sure she can take care of herself" Seulgi said

"Oh I see, that's why you can't score with your girlfriend Yongsun-ah!" Irene laughed and Seulgi quickly covered to shut her up

-- "Ahhh, so you guys are those 'friends' who told Byul about thing within couples?? I can't believe it" Yongsun rolled her eyes. She started hitting Seulgi's arms "We almost had a fight because of that, why do you keep running your mouth? Are you crazy?" 

Irene is covering her girlfriend "Yah! Kim Yongsun! stop hitting my Seulgi!" 

Yongsun calmed down and the couple across her started laughing

"You really didn't do it yet, didn't you?" Irene said laughing

Yongsun sighed "Okay, we didn't. I just don't want our relationship to revolve around , Irene you know my past"

"I know, but Byul is different from your exes, she doesn't want your money nor your body, she wants your heart Yongsun-ah" Irene said. Yongsun melted hearing it from Irene.

"Unnie if I were you, I would reconsider it. You guys are only gonna do it once, consider Byul's feelings too, give her some experience at least, especially now that Byul will soon go to Seoul, I'm sure you're aware that-" Seulgi spoke and was cutted out when Irene pinched her in the thigh.

Yongsun only smiled bitterly.

"Why is your girlfriend taking so long?" Irene spoke, changing the topic 

-- "She said she's almost here" Yongsun replied as she glanced at Byul's last message

The food is already served to their table, Yongsun started eating while the couple were busy with each other. 

"Unnie, Byul's here" Seulgi said, looking at the window.

Yongsun's eyes widen when she saw her girlfriend, she's sharing an umbrella with a guy. The guy is looking lovingly at Byul, caressing her hair, and holding her in the waist as they cross the road. Yongsun was gritting her teeth, her face turning serious, she's mad.

"Oh, that's Choi Minsook" Seulgi said

-- "Choi Minsook? she never mentioned him to me" Yongsun replied

"Ahhh, he transferred last year, he's in the same class with us. Don't worry unnie, they're not that close" Seulgi said, trying to mind her words to not cause any misunderstanding

-- "Well, it looks like it doesn't seem to be the case" Yongsun said in monotone

Seulgi felt that Yongsun is quite not happy with what she saw  

"Well, Byul is not that open about her personal life so only a few people know that she's in a relationship. It's inevitable, she's charming and she has a perfect personality, but don't worry unnie she doesn't care about them" Seulgi defended, laughing nervously

-- "That Minsook didn't know about us?" Yongsun asked

"Uhm, I don't know the details but he confessed to Byul last year but obviously he's rejected. I'm sure he knows about you unnie, everytime Byul opens it's always 'Yongsun did this, Yongsun did that'."

-- "but he still clings to Byul after knowing that? What a thick-skinned dirty scumbag!" she said, feeling irritated. She continued munching her food

"Yong!" 

The trio turned their heads. They saw Byul rushing to their table.

Byul hugged Yongsun and gave her a kiss.

"Hey, Irene unnie! How's work?" Byul asked as she positioned herself comfortably to sit

-- "Good, just the usual, nothing new. Are you hungry Byul? You can order as much as you like, my treat" Irene replied

Byul noticed that Yongsun is giving her a silent treatment

"Yong, are you okay? Tired?"

Yongsun only nodded. "Did you came alone?" she asked, expecting Byul to answer honestly

"No, I forgot my umbrella so a friend offered to accompany me" 

-- "A friend?" Yongsun asked

"Yeah, he said he had some business around this area too" Byul replied.

"Choi Minsook? Did you actually believed that sh*t?" Seulgi asked

"How did you know it's Minsook?" 

"I saw you" 

They talked about school, work, gossips, and their plans. Everyone was laughing except Yongsun. Byul didn't missed that.

"Yong is there a problem? Are you sick?" Byul whispered

-- "I'm fine, let's just go home after this"

After minutes of talking, eating, and enjoying their free time, Irene induced everyone to go home

Yongsun said goodbye, she walked to exit without looking back.

Byul is about to leave too when Irene stopped her. 

"Byul, Yongsun saw you with that guy earlier, I think you two should talk" Irene said

Byul was flustered "thanks for telling unnie, maybe she misunderstood. Goodbye Unnie, bye Seulgi!"

"I can see their first fight coming" Seulgi said

-- "First fight?" Irene asked

"Yup, they never fought before"

-- "They can fix that, those two are attached at the hip, they can't live without each other" Irene replied

Seulgi squeezed her girlfriend's hands tighter.

Byul then rushed to Yongsun's car, parked in front of the coffee shop.

"What took you so long?" Yongsun asked, irritated

-- "Sorry" she said, pouting her lips

Byul kept initiating a talk inside the car, thinking of numerous topic that will make Yongsun speak to her. The older is still giving her a silent treatment, only nodding to everything she says.
