Lee Selena is a professional makeup artist and the older sister of Lee Suho. She first appears in the story as the idol and role model of the protagonist, Lim Jugyeong, who has admired her since high school for her exceptional makeup skills. Selena has a striking appearance with straight, mid-back length blonde hair that features a pink ombre at the ends, styled with bangs swept to the left side, and hazel eyes. Her background as a celebrity makeup artist makes her a respected figure in the beauty industry, and she becomes a key source of inspiration for Jugyeong. Selena’s personality is portrayed as skilled, confident, and supportive; she encourages Jugyeong to pursue her own passion for makeup artistry, reigniting the dream that Jugyeong had set aside. In the story, Selena plays a supportive role: she is a family member to Suho, though they have different last names for reasons that are not fully explained in the narrative, and she later becomes a mentor and employer to Jugyeong. Her development is primarily seen through her influence on Jugyeong’s career path, as she provides professional guidance and helps Jugyeong rebuild her self-esteem. Selena’s notable ability is her mastery of makeup techniques, which she uses not only to transform appearances but also to empower others, embodying the theme of inner beauty and confidence that runs through the series.
