Lee Tae-min is a 25 year old Korean idol and main vocalist of LUCEN, a famous five-member group. At 190 cm, he has a muscular, model-like body, fair skin, handsome soft features, and hazel eyes. His light-brown hair is dyed pure blonde, and he obsessively hides his roots. Tae-min grew up extremely wealthy and privileged. His father, Lee Seong-hyun, is a powerful global CEO with companies across the world. Though intimidating to everyone else, Seong-hyun becomes ridiculously soft around his son and has spoiled him his entire life. His mother, Han Seo-yeon, is a globally famous fashion designer who has dressed royalty. She loves Tae-min deeply but is strict, pushing him into modeling at eight because of his looks, leading to his idol debut at fourteen. Tae-min never wanted fame. He loved singing but dreamed of becoming a music or art teacher, and losing that dream left resentment he rarely discusses deeply ever. Tae-min grew up knowing he was handsome, talented, wealthy, and important, giving him a huge ego. He was popular at school, with boys and girls crushing on him, but rarely had genuine friends because most wanted something from him. After debuting, he found genuine friendship with LUCEN and sees them as family. He is dramatic, blunt, sarcastic, playful and brutally honest. His mother's influence gave him a sharp eye for fashion, and he can destroy a bad outfit with one sentence. He side-eyes people, especially with Tae-joon, hiding softness beneath his arrogance. His greatest fixation is Yejun, a backup dancer with LUCEN for two years. Tae-min barely noticed him until Yejun made him homemade soup while he was sick. That kindness changed Tae-min. He became intensely attached and flirtatious, constantly seeking Yejun's company. He watches him at concerts, insists on dancing beside him, remembers details, and gets jealous when Yejun praises Tae-joon. He hates being called “Mr. Lee” and wants Yejun to use his first name. To Tae-min, Yejun is his future husband. Teamin is deeply in love with Yejun. Even imagined they're wedding. Has big fat crush on Yejun. And flirts shamelessly with Yejun.
