Chaeyoung knows what she feels right now is jealousy. The feeling of something squeezing her heart is a sign of jealousy. She knows Jeon Jungkook is famous among the students and mostly female, she used to not feel anything seeing him talking with other female students. But now she can't.

She shouldn't feel jealous - she tells herself.

Jungkook had told her that he had a group assignment, he always told her about the people around him, to make her familiar with his friends and classmate. Sometimes he took her with him to meet his groupmate.

So why she felt jealous when she saw him with his group assignment? Well maybe because half of the group was female students...and they're pretty too. She saw and heard how Jungkook exchanged conversations with them about cinematography and camera accessories...she can't grasp what they are talking about and somehow Chaeyoung felt left out.

She's the one who decides to not join him with his group anymore, so why she felt like this when she saw him a few tables away in the cafe laughing and chatting happily with his group?

Chaeyoung knocks her chest a few times, trying to push away the squeezing on her heart.

"Are you okay?" Min Yoongi looks at Chaeyoung, concerned.

"Hmm? Ah, I'm okay. I think I eat too much earlier...my chest hurt." She lied. Her hands continue arranging the flower in the vase. She had promised him to help decorate his cafe with flowers.

Yoongi didn't say anything, but walking to the drawer near the cashier counter. He pulls out a small sachet containing herbal tea from the drawer and puts the teabag inside a cup of hot water.

"This is herbal tea, it's good to treat heartburn.." he handed the cup to Chaeyoung.

She takes it with a giggle. She knows what she felt is not heartburn but it's okay as long as he doesn't know that she was just jealous.

Jungkook's ears twitched when he heard a familiar giggle not far from him. He turns his head to look at the counter. Chaeyoung was taking the cup from Yoongi's hand. They both chatting with a smile on their face.

He noticed, he watched her the entire time. He watched every interaction, every word, smile, and laugh that left her lips this whole time. Even tho he's busy discussing with his group, he always watching her from the corner of his eyes. Every time Chaeyoung smile at the male customer who came to the counter, it made him press his mechanical pencil much harder on the paper till the pencil lead break a few times.

Jungkook knows he is whole-heartedly jealous. He's jealous when Chaeyoung didn't look at him, he feels that almost familiar burning pit in his stomach. The same feeling when he saw her wore Vince's jacket.

He doesn't like the feeling in his stomach right now. He really wants to pull Chaeyoung and make her sit close to him...within his reach.

He feels relief when one of his groupmates suggests they stop the discussion for today. Without waiting for them to leave, Jungkook already stood up and walks to the counter, Chaeyoung has her back facing him. Shamelessly he gets inside the counter ignoring the way Yoongi looks at him. Jungkook moves over to where his girlfriend stood, sliding his arms around her waist and placing his chin on her shoulder.

Chaeyoung was surprised with the sudden PDA but her body automatically melted against him. She smiles at him. The tight-squeezed in her heart that she felt earlier immediately vanished.

"My group discussion had ended. Should we go somewhere for lunch?" Jungkook asked.

Chaeyoung frowns because she could hear the pout in his voice. She wonders why. But after a few seconds, her eyes went big after her brain repeated Jungkook's question about going somewhere for lunch. That's how she realized they're in Yoongi's cafe and the owner was THERE talking to her earlier...

Her face burning red when her eyes look at Yoongi...and he was looking at Jungkook with distaste eyes. Chaeyoung quickly removes her body from Jungkook. She was embarrassed.

"Okay. But give me a few minutes...I'm going to the restroom." Chaeyoung replies without looking at her boyfriend.

Jungkook chuckles looking at Chaeyoung retreating figure.

"Gross..." Yoongi glares at Jungkook. "You better stop coming to my cafe if you want to be touchy with your girlfriend. I don't want to receive any complaint about public indecency from my customers." He throws a small ice cube towards Jungkook. It hit the younger's chest.

Instead of feeling hurt, Jungkook laughs. He doesn't care, as long as everyone could see who it was that could hold Park Chaeyoung and keep the smile on her face, that was all he really cares about.
