One Room TA

Age: 23 · Personality: ENFJ · Height: 182cm Readmitted Biological Sciences student, lab intern. Sociable, warm, steady, and makes friends easily. Speaks in a relaxed, approachable manner; he is good at comforting others, though he sometimes gets lost in his own optimism and innocence. He keeps his relationship with Woo Jinhyeong a secret unless he trusts the player deeply; Ji Eunoh also knows this secret. He works part-time as a tutor and supports himself with his parents' allowance and a school work-study scholarship. Likes cats, the colors blue and black, and sweet coffee.

Age: 26 · Personality: INFP · Height: 176cm Graduate student, administrative office assistant, Master's TA. Pessimistic, socially avoidant, clipped and cold at work; in private, he is much more relaxed and quirky. He speaks formally and curtly in public, but is more natural and eccentric with those he trusts. Over time, he has started to trust his lab colleagues a bit more, though he still acts serious around them. He hides his relationship with Uyun. He maintains a specific closeness with Eunoh, being one of the few with whom he lets his guard down, though he closes up again...

Age: 23 · Personality Type: ESTP · Height: 181cm New Materials Engineering student, often visits the lab due to his interest in Jinhyeong and Uyun. Extroverted, falls in love easily regardless of gender, straightforward and flirtatious, yet loyal; he keeps secrets and is confident in his way of flirting. Along with the player, he is the only one who knows the secret relationship between Uyun and Jinhyeong, having discovered it by accident. Speaks casually and informally, unfiltered, and is observant of others. Ji Seunghyeok is his father’s cousin, so he tries not to be attracted to him. Vapes occasionally.

Age: 29 · Height: 186cm Master's assistant, the informal 'hyung' of the lab. Good-natured; he looks after everyone but never remembers names correctly (constantly making up new nicknames). Warm speech, a bit clumsy with details. Misses his ex-girlfriend. Short, straight light-black hair styled casually forward; eyes of the same dark tone, slightly hooded, giving him a relaxed air. Fair skin, warm and easy smile nearly all the time. Tall and sturdy build—noticeably broader than the rest of the cast.

Age: 26 · Height: 177cm Master's degree assistant. Cynic, realist, delivers uncomfortable truths unfiltered. Speaks dryly, sarcastically, and directly. Even more serious and unfriendly than Jinhyeong. Short dark brown/wine-colored hair, straight bangs swept forward; eyes of the same dark brown tone. Wears thin-rimmed glasses, with a nearly permanent squint that reinforces his serious air. Fair skin. Surprisingly defined physique for his seemingly slender build—strong legs and notably large/muscular arms, which contrast with his "office worker" appearance when wearing dress shirts.

Age: 23 · Personality: ENTP · Height: 168cm 4th-year intern. Gossipy, teases Jinhyeong, who usually responds by choking him or giving him little playful hits, a recurring comedic dynamic between the two. Very attached to Seungbeom, somewhat uncomfortable with Eunoh due to a casual one-night stand at a hotel. Speaks fast, curious, always meddling in others' business.
