Sulli looked at the dishes she prepared for tonight's dinner and smiled in satisfaction.She knew right away that her mom and dad will love all the food she cooked and baked for tonight,even the table setting was perfect.

Everthing was perfect until....

"Irene!"

She froze upon hearing her mom calling the name of the woman she despised all her life.Before that woman came into their lives,Sulli was her parents world,she was the center of their attention of everyone around her,she was the pretty,smart and talented child of them but everything changed when her parents decided to adopt an orphan named Bae Irene.From being the apple of the eye of everyone she woke up one day and found herself being relegated as "the other sister", the real child of Mr John and Mrs Jane Choi who was the lesser version of their adoptive child.Though their parents tried their best to give equal attention and love to both of them,she felt that as the real child she should get more and less for Irene.

"Mery Christmas mom...dad"

She almost roll her eyes in annoyance while listening to her adoptive sister cheerful voice.

"I missed you honey" her dad said

Sulli's hands balled into fists.She hated it everytime her dad was being sweet to Irene,she used to be her dad's one and only girl but eversince her adoptive sister came into her life,she felt as though her dad loves Irene more than her.

"Mom..Dad..my my friends"

Curiously,Sulli took a peep from the kitchen to the living room and saw Irene still beautiful as ever introducing three of her friends to her parents.One of them a tall man in denim jacket who's back was facing her.

"This is Wendy" her adoptive sister introduced,referring to the blonde petite woman standing beside her.

"...and this is Joy" the tall woman with long raven hair took a step and shook hands with Mr and Mrs Choi.

"...and Minho" one of Sulli's brow lifted as she saw how Irene's cheeks blushed while her "friend" Minho and their parents shook hands.

"Please to meet you sir...mam" 

For some unknown reason the man's deep voice sent chills down her spine.

Irene caught her looking from the kitchen and smiled hesitantly.

"Oh and there's my...my sister Sulli" she said,biting her lower lip awkwardly.

Everyone looked at her including the guy named "Minho".

Sulli just nodded at them,her eyes zeroid in on the attractive man but after giving her a polite smile Minho's attention returned to Irene.She witnessed how her adoptive sister's eyes sparkled while looking at him and how her smile for him radiated across the room.She hated it.She hated seeing Irene happy while she on the other hand was miserable and empty.She hated seeing how everyone made Irene feel special while she was the lonely "other sister" everyone ignored.

She turned her back on them and stared at the food she prepared for her parents.A bitter smile on her lips as she felt like a loser again and that all the hardwork she did for tonight's dinner was wasted because of Irene who was consistent of stealing everything from her eversince.

She remembered the way Irene looked and smiled at the guy named Minho and she knew right then  that he was somehow special to her.Suddenly,a plan crossed her mind.

This was the moment she was waiting for,the perfect moment for Bae Irene to pay all the pain she unintentionally inflicted on her for so many years and she will use Minho to get back at her adoptive sister.
