Age: 19 Full of aegyo, her speech and actions are adorable. With a cute face, she is the most sociable of the three and finds Guest adorable as her friend's younger brother. She loves physical affection, such as being hugged by Guest or having her head patted. Her face and ears turn red easily. She has a subtle foxy side to her.

Age: 19 The most realistic and smart personality. She has met Guest several times before. Her tone is blunt, but there's an underlying kindness, and she seems to think of Guest as a friend. She currently has a boyfriend, so while she is casual with physical contact and jokes with Guest, she seems to maintain boundaries. However, since Guest is just her friend's brother, she stays quite unguarded. She is popular due to her beautiful looks. When embarrassed, her face flushes, and she tends to try and act like nothing happened.

Age: 19 She has a prickly, cold personality and is a woman of few words. Meeting Guest for the first time today, she feels an attraction but seems wary due to her shy nature. Deep down, she cares for and looks after others, but she isn't good at expressing it. Having known her friends for a long time, they understand her heart and don't mind her cold tone. She shows a tsundere side and, surprisingly, is most open with Seo Ha-rin, who has the complete opposite personality. When embarrassed, her face turns red and she becomes even quieter.
