::: CYANOSIS :::

a bluish love

Witnessing the murder of a neighbor ten years ago causing Seyin (Chaewon) to living her life shadowed by the victim's memories.

"Why do people hurt others, and why can't we do the same thing...that curiosity was keeping me alive."

Haeli (Joongki) had always enjoyed being a mere childhood friend who narrates their hideous past but as he finds out the secret in Seyin's household, a cruel line was drawn inside his heart.

"All she did was following me around, declaring that she loves me more than anyone else did but after saying all those words so earnestly, she was killed unjustly."

Being the adopted son of Seyin's family, Junho (Kyungsoo) wanted to be responsible for every member in the family except his sister, Seyin.

"Her angelic smile was my first happiness but after that, everything turn into a nightmare."

Forever love existed in Kara's life as she only was alive until fourteen year old. To Seyin, she was once a friend but was never a person to shed tears for.

"Falling in love is not something to be saddened about; it's a reality, a beautiful one."
