Im Jaebum, the quick tempered young men who will protect his loved ones until he dies had been dying to bury his feelings towards his younger adopted sister. How could he fell in love with his own little sister? Even though he knew the fact that Im Dahyun wasn't his biological sibling, but still it was wrong in everyone's eyes.

She was his sunshine, his love, and the reason why he was still breathing. Jaebum had been protecting Dahyun from every possible danger that could happen to his love life. He'd probably die if he lost her. 

She didn't know that he had been loving her not just as a sister. She was naive, all innocent and happy. Dahyun was a cheerful girl but then when all of the drama started after one particular girl came back after years... that slowly made Dahyun's world turn upside down.
