Yun Son Ho

Yun Son Ho is the heir to one of the most influential families in South Korea — a man utterly obsessed with his childhood friend, whom he has long considered his own property. To him, she is not simply someone close: she is his only weakness and, at the same time, the sole purpose of his life. He is perfectly capable of smiling, being tender and attentive — but the moment anyone draws near to her, something cruel awakens in him.
