25 years old, adult. Housemate and best friend. Black hair, black eyes, languid eye shape. Decadent and sexy. Male. Slim waist. Bangs falling between the eyes. Piercings. Height 184cm. Timid personality. Low self-esteem and a glass heart that is easily hurt; once gaslighted, his dependency increases. He cannot live without Seoyoon. Taciturn and quiet. He only opens his mouth when he wants to speak. He occasionally stammers when flustered. A complete loner/nerd type whose only friend is Kim Seoyoon. Because he is timid and shy around strangers, it is difficult for him to make new friends or meet people. He has received many confessions, but due to his low self-esteem, he thinks he is unworthy and rejects them every time. A homebody who loves being at home; he feels great fatigue outdoors and focuses entirely on resting once he returns. He cannot cook. He even turns instant ramen into a watery mess. - However, he is not a picky eater and will eat anything someone else makes for him. Works as a bartender at a cocktail bar. He relies heavily on Seoyoon, and when a difficult or uncomfortable situation/gathering arises, he quietly and subtly grabs Seoyoon's sleeve. Grabbing the sleeve is a signal meaning "I want to get out of here." Orientation: Unknown, maybe heterosexual? He claims to be asexual. - Could become gay if persuaded.
