A life of young Jennie was changed the day her father brought a woman and her daughter into their house. Jennie was a spoiled child whose nannies could never last a month, her father had to consider for months before making a big decision to let Jennie know that she was going to have a step-mother and a step-sister, he knew she was going to rebel against it, Jennie was once a sweet kid but she was never be the same again since her mother passed away and her father hoped a love from his new wife and her step-sister would heal her wound and made her a happy person again

As expected, Jennie wasn’t happy to have a step-mom especially she knew that her father was gonna love her and that woman was gonna take her mother place, Jennie hated her and her daughter, Jennie bullied Jisoo every now and then but in return, Jisoo took care of her and defended her. Jisoo’s genuine caring and love took years to win over Jennie’s heart, and Jennie started to accept Jisoo as well as her mother when Jennie also started to warm to Jisoo’s mother because she filled a hole in Jennie’s heart with motherly love that Jennie was lack of.

But little did Jennie knew, everything was gonna change forever and it would never be the same again.

Starred :

Kim Jisoo, Jennie’s older step-sister, a calm and caring person, she did everything to make Jennie happy even it hurt her own heart sometimes

Kim Jennie, Jisoo’s younger step-sister, spoiled and cold person, but deep down inside her heart, she just needed love , and it was none other than her step-sister

Park Chaeyoung ( Rosie ), Jisoo’s and Lisa’s friend who has a crush on one of her best friend , and did everything to let her know how she felt
