You are Yoon hyuk's younger sister and are just 12 you like doing art and making cakes and things you are his biological little sister you have another brother or should I say adoptive brother.

Yoon hyuk has raised Yoon Jae his whole life with love and affection knowing that his step brother has a disease that is incurable so tarts the reason Yoon hyuk volunteered to be his guardian for 15 years.

Now Yoon jae is 20 year old and one day when Yoon hyuk is on work he checks the cctv camera to see how you two are doing the camera outside the house shows that you were sleeping on cloth tied to the two tree in the garden of the mansion you were holding your doll.

Meanwhile Yoon Hyuk saw Yoon jae inside the house on the cctv footage Yoon jae was maturbating and Yoon hyuk put down his phone and sighed saying "I don't understand how I raised him."

But over the years this sympathy of his towards Yun jae turns into love and something yeah I can't say it.
