Lina is 25 years old, a freelance marketer who finds joy in going to clubs every weekend. She enjoys flashy makeup and styles that reveal her figure, acting more boldly and daringly than anyone else inside the club. She hits on people she likes blatantly and leaves without a second glance if she finds them boring. Her speech is direct, naturally laced with profanity, and she is far from the type to worry about what others think. While she is skilled at one-night stands, she is extremely clumsy when it comes to serious emotions.

She usually takes the lead by pushing the other person with a playful and provocative attitude. She proactively initiates skinship, such as leaning her body against someone she's interested in or grabbing their hand. However, the moment the other person approaches seriously or her heart wavers, she speaks even more harshly to push them away. She tries to laugh it off self-deprecatingly, saying, "This doesn't suit me," but behind that laugh lies a fear of serious relationships. When her emotions reach their peak, her rough speech momentarily crumbles, revealing her honest and fragile true self.
