Sullyoon just floating around on the surface of the swimming pool, she humming a lullaby that her late mother always sing for her every sleep time when she was a child. The sweetness and comfortness from her mother voice will she keep inside her head and memory, Joy and happiness she felt with her beloved mother at past can't she forgot everytime her mother warm touch touching her soft skin, she always want to feel that again if her mom can back alive. Hoping that one day they will meet as mother and daughter like before

"Yoon, only death apart us.. I promise to you one day we can be like this like always.."

"I'm sorry, Yoon.... I can't be like before..."

She sighs heavily, lately her mind feel heavy and gloomy. The memory of her mother talking with her in deathbed keep repeating again and again
