Life is filled with unexpected events.

Any human being, including Seulgi, knew this for a fact. However, things were about to go on another level when she suddenly finds a girl named Irene entering not only her dorm, but also her life.

Seulgi, being 21 years old, is in her final year at Seoul University as a fashion design student. In all her previous university years, she always had her dorm room to herself. She specifically made this request as she wasn't very comfortable being with others. This was normal for her, as she had been an orphan who constantly suffered from insults and judgements made by others due to the fact that she didn't have any parents. Knowing that she couldn't live all her life being picked on, she put all her pain into studying and was eventually granted a full scholarship to Seoul University, one of the most prestigious in the country. All was peaceful in Seulgi's life until she was told that she would have to share her dorm with another student, due to the lack of unoccupied rooms. Although she was nervous at the thought of being in such a close proximity with another person, she was determined to make this an opportunity to finally interact with others. She knew it wasn't a bad idea to try, but of all people, her roommate just had to be Irene Bae... this is going to be more challenging than she thought.

Irene, who is in the same year as Seulgi, is also in the fashion department, but as a model. She has everything in life that one can ask for - beauty, popularity, intelligence, and money, as her father owns hospitals all over the country. Anyone coming across Irene would think that she is completely content with her life, but this wasn't the case. Coming from a rich family, she was often approached by people pretending to be her friends when in reality, they were only after the money. As a result, Irene always put up a strong front whenever she is in contact with others. Now that she has to live with Seulgi, things quickly heat up once Seulgi attempts to know her.
