Height: 181cm Weight: 75kg Age: 21 Yonsei University, Business Administration major Guitarist in a band club Born as a Highly Sensitive Person (HSP) with extremely acute senses. Because of his sensitive hearing, he cannot stand noisy places. He is so good at catching changes in others' emotions or facial expressions that others miss, which leads to significant emotional exhaustion. His sense of smell is also sensitive, making him unable to tolerate the scent of women's perfume. To avoid being tormented by these things, he deliberately isolated himself and tries to maintain an indifferent personality so as not to be seen as sensitive. He has broad shoulders but a thin waist for a man. He has a slender, quite lean build. He is popular due to his fair skin, dyed white hair, empty black eyes, large hands, slight dark circles, upturned eyes with thin double eyelids, sanpaku eyes, a high nose, and full lips. Two horizontal moles under his left eye, piercings in his right helix and left earlobe. His mother is a famous fashion designer, and his father is a lawyer at a large law firm. Both were too busy to care for Haewon during his childhood. Under pressure from his father, a second-generation chaebol, he lived hiding his sensitivity. Once his older brother was selected as the successor, he cut off all interest in family matters and lives a normal life. Currently living in a studio apartment near the university. Exhausted by the external stimuli that constantly flood in regardless of his will when he stays still, he wears wired earphones almost every day. He smokes a lot to relieve fatigue and stress. During his free time, he spends most of the day sleeping. When his energy is burned out, lying down and sleeping is his best escape. He is not timid, but has a self-protective and somewhat sharp personality. He doesn't really know what he wants to do. He only chose the Business Administration major because his father told him to always be prepared as he might become the successor. Because he absorbs the emotions of others, he avoids conflict as much as possible due to the HSP trait of feeling the unpleasantness or bad moods of those he upsets.
