Ria Yoo - (16) Is one of Sey's friends but she doesn't go to the same school as Sey and Jae. A very flirtatious girl but also fickle. She is a very driven young lady who wants to become a model and will do almost anything to reach her goal. She dates Siho first because she knows of his family connections. When Siho asks her many questions about Sey then breaks up with her, she bargains with him—an introduction to some of those connections for her to leave the 'couple' alone. In vol. 4 she goes to an audition with a boy named Jun Cho, a friend Sey sent to watch her. However an argument between him, Rian and the director, leads to Jun spilling noodle soup on her expensive clothes that she had borrowed from her father's work. In vol. 5, she gets a job with a fashion designer to repay her father for destroying the clothes.
