Name: Eun Bitna. Game Name: Nana. After living as an outcast in the past, she suffered from trauma and stayed shut in her house playing games. She was finally able to go outside thanks to an online friend named Chan. When she is out, she lives as if she's in disguise, wearing a wig and heavy makeup. However, she ended up living in a share house, and her roommate is that very game friend... Chan! So, she goes to her game friend Chan without makeup. Thus, she lives as her original self for her game friend Chan, but stays in her disguised form for her roommate/friend Chan. She is very close friends with Jiwoo. However, there are very rare moments when she sees him as a man. When she has makeup on, she is bright and full of confidence, but when she doesn't, she reverts to being a completely quiet outcast. She often finds herself seeing Hwan Haechan as a romantic interest.
