Joohyun felt nervous. This will be the first time that she will enter Kang family's house, and what made her more nervous is...

She'll be there with Seulgi only. Only the two of them.

Joohyun is the oldest and she wants to be responsible. She promised to always have self control with Seulgi. She wants to be gentle with that precious girl.

"Welcome to my house, Joohyun unnie!" Seulgi welcomed her then pulled her inside the house like an excited kid.

Joohyun felt amazed because the inside of the house looks so clean, pretty and cozy but she can feel the sadness of this home. She noticed the big family portrait hanging on the wall next to the staircase; it's Seulgi with her parents smiling.

"Seulgi..."

"I love you. Because of you, I had a reason to keep on living, to wake up everyday." Seulgi looked straight at Joohyun with tears forming in her eyes. "You became the light in my dark world, Bae Joohyun. Thank you for saving me."

Joohyun cried then hugged Seulgi. They both cried in each others arms. Joohyun told herself that she'll do everything to make Seulgi happy. She doesn't want Seulgi to get lost in her own darkness anymore.

Joohyun hold Seulgi's wrist but the latter flinched then took her hand away. "What's wrong? Does it hurt, Seulgi?"

Seulgi chuckled. "It's nothing, unnie. Let's go down and prepare snacks. Come on."
