On a sunny Sunday, Kim Sisters started their day peacefully until Doyeon started to come out from her room

"Unnie~ !!! Good morning!" Doyeon said happily

"Morning Doyeon, you look very cheerful this morning" Chungha smiled at her sister

"Unnie it's Sunday, time to go on a picnic. Yeah, isn't Taeyeon unnie?"

"Hmmm" Taeyeon humming while preparing their breakfast

"Where is Sejeong? I haven't seen her since I woke up" Nayoung asked while tidying spoons and plates

"She is still in the room" Chungha answered

"Sejeong unnie is still sleeping? This should not happen, if she continues to sleep, today's picnic can be canceled" said Doyeon

"Try to wake her up" told Nayoung

Doyeon quickly got up from her chair and went to Sejeong's room

"This is an unusual thing, why is she moving so fast like that?" Chungha laughed

"That's because she don't want the picnic she expected to be canceled" said Taeyeon

Doyeon went in to Sejeong's room and saw her still sleeping under her blanket

"Sejeong unnie, wake up!" she walked towards her

"Unnie, hurry up. It's Sunday and we will go to picnic" she shook her body, but Sejeong was still in her deep sleep.

Doyeon then climbed onto the bed and hugged her sister "Sejeong unnie~ wake up~"

Sejeong just groaned "Hmmmmm"

"Unnie, wake up... wake up... wake up..."

"Doyeon, please stop it. Let me sleep"

"Unnie you have to wake up now, we will go on a picnic. You have to get ready" she said with enthusiasm

"Hmmmm"

"Unnie, are you sick?" Doyeon said when she heard Sejeong's voice was weak

"No, I just need a sleep"

"Unnie, are you sure? You okay? We can cancel this-" she worried at her sister

"Don't worry, we will still going. But for now can you let me sleep just a little longer, please Doyeon" she said in a sleepy voice without opening her eyes

"Really unnie?"

"Hmmm. Now get out and let me sleep" Sejeong pulled the blanket that had been pulled by Doyeon before

"Okay" she came out of her room

Doyeon left the room with a sad face, she thought the picnic this time would be canceled

"What's with your face Doyeon? Where's Sejeong?" Nayoung asked

"Unnie, it looks like Sejeong unnie is sick" she was sad

"Sejeong is sick?" asked Taeyeon

"Yes, her voice sounds like a sick person but she said she only needs to sleep longer. I'm worried. Will we cancel the picnic today?"

"Don't worry Doyeon, we will still go, with her too. Sejeong is just a little tired, she was too busy with her activities on campus since yesterday morning. Let her sleep, I'll wake her up later" explained Chungha

"That kid is always concerned about her activities than her health" said Taeyeon

"But is she really okay?" asked Nayoung

"I'll check her later, now let's eat" Taeyeon put food on Doyeon's plate

It's 10am. Kim sisters tidying up the food they would bring, preparing all things for the picnic. While Doyeon was in her room, she still doubted whether she should force her sisters to go on a picnic or not, because all of this was her idea. When Doyeon was daydreaming, Sejeong knocked on the door of her room

"Doyeon, can I come in?" Doyeon did not answer, Sejeong then open the door and immediately entered

"Doyeon" called her "Doyeon..." She still didn't give a respond "Kim Doyeon" Sejeong patting her shoulder

Doyeon was surprised "Oh unnie, you surprised me"

"Why are you daydreaming?" Sejeong sat next to Doyeon

"Ah, are you okay unnie? We can cancel this picnic if you are sick"

"I'm fine Do, you are the one who don't seem to be good. What's with your face, this is the picnic you want but why do you look sad?"
