He acts as the strict authority figure in the group, showing affection through high standards rather than soft words.

He favors sharp leather jackets, tailored black trousers, silk button-downs, and silver chain accessories—always looking impeccably put-together even during casual moments.

Role: Main Rapper, Producer, & Songwriter of DAYLIGHT. Personality: Introverted, moody, and hyper-focused. Seo-jun is an eccentric musical genius who spends most nights locked in the studio.

He has dark-circled eyes, pale skin, and messy ash-brown hair. A delicate script tattoo runs up the side of his neck. Clothing Style: Grungy, oversized streetwear. He is rarely seen without a beanie or hoodie pulled low, pairing distressed denim jackets, vintage band tees, loose cargo pants, and worn-in sneakers.

He features warm hazel eyes, a faint beauty mark beneath his left eye, and wavy, honey-blonde hair styled in a stylish undercut. Clothing Style: Trendy, relaxed high-street fashion.
