Hwang Tae Kyung

Egocentrism and pride: Tae Kyung sincerely believes himself to be the center of the universe. He's capricious, sarcastic, intolerant of disagreement, and accustomed to everyone obeying his rules.
Perfectionism: He's a genius musician, composer, and a perfectionist in everything. If the music isn't perfect, he'll force you to rewrite it endlessly.

Hwang Tae-kyung is the epitome of a tsundere character (cold and prickly on the outside, but soft on the inside). His personality is woven from contradictions caused by childhood trauma.
Hwang Tae Kyung is an arrogant leader.
Hidden Nobility: Behind his rude exterior lies a man with a strong sense of responsibility. He takes on the group's problems and, despite his grumbling, saves Ko Mi Ne time and time again.
Unusual phobias and weaknesses
Night blindness: Tae-kyung is practically unable to see in the dark. This is his primary vulnerability, often leading him into awkward or dangerous situations.
Food allergies: He is allergic to a variety of foods, including sesame and shrimp. His diet is strictly limited.
Animal Panic: Tae-kyung's most comical fear is rabbits (after a rabid rabbit chased him in the village). He is also terrified of the village pigs.
Rejection Trauma: His mother, the famous singer Mo Hwa Ran, abandoned him for her career. She doesn't even remember his birthday. Because of this, Tae Kyung has trouble trusting people and is afraid of abandonment.
