Today was a heavy rain day, lightning, thunder, repeatedly snatching, dark skies, streets filled with people walking with their umbrellas.

Nayoung arrived at home with her wet shoes because the rain on her way to home.

"Aish.... damn my new shoes are wet in a day" she muttered, irritated. She took off her shoes and put the umbrella near the entrance door.

Nayoung entered the house, dark, the lamp had not been . She the lamp in the TV room and then put her body on the sofa, relax.

"Where is everyone? Are they all stuck because of the rain?" Nayoung asked herself because she didn't see anyone at home, she took her cellphone from her jacket pocket. Suddenly a thunder sounded loud. She was surprised

*Duarrrrrr*

"Ahhhhhhhhh!!!!! Sejeong unnie!!!!"

Nayoung was surprised, heard a thunder sound and a shouted simultaneously. She got up from the sofa "Doyeon?". Yes, she heard Doyeon screamed and  she rushed to her sister's room.

She opened the door and saw Doyeon looking down, her hands hugging her legs, trembling, scared.

"Doyeonah, what happened?" Nayoung asked, walking closer to Doyeon

Doyeon raised her head and cried after seeing Nayoung "Unnie... hiks hiks..." Doyeon hugged Nayoung tightly

"Hey, why? Don't cry" she rubbed her sister's back

"I'm scared, the thunder is so loud" Doyeon answered

"That's okay, don't cry. I'm here" Nayoung said softly, caring. Doyeon was still sobbing, still holding her cellphone

"Doyeon, are you okay now?" Nayoung took off her arms, looked at her sister and wiped her tears

"Hmm" Doyeon nodded

"You are crying, scared, but still have time to hold your cellphone? You'll update a status on your sns about this situation?" Nayoung said while laughing, joking

"No! I called Sejeong unnie, but her cellphone is dead"

"Sejeong? Why did you call her at a time like this?

"I slept well, but I woke up after I heard the loud thunder. I was scared and called Sejeong unnie"

"You're calling Sejeong just because of the thunder? Hahahahaha you are a scared cat" Nayoung laughed at her sister's act

"Don't make fun of me. I'm scared of thunder unnie, and you know it" she looked at her sister, "I have to listen her voice whenever I'm scared of it, but this time her cellphone is dead. I can't get rid of my fears."

Since they were kids, Doyeon was scared of the sound of thunder. Her sisters knew it, but as long as there were other people beside her, Doyeon was fine. One day Doyeon was playing alone in her room. Suddenly there was a lightning, followed by the sound of thunder, so loud, she screamed. At that time there was only Sejeong studying in her room. Sejeong who heard Doyeon's scream immediately ran, she hugged her sister tightly.

"Calm down Doyeon, I'm here"

"If you're scared, call me. I'll come and hug you faster than that lightning, get rid of your fear"

"If I'm not there besides you, call me. I'll sing for you so that fear will disappear"

There are the words Doyeon always remembers until now and this is a habit for her to call Sejeong as a first person whenever she scared of thunder.

"Okay I am here now, so you don't need to be scared anymore. You better go back to sleep, I see you're very tired" Nayoung to
