One Room TA

Age: 23 · Personality Type: ENFJ · Height: 182cm Readmitted Biological Sciences student and lab intern. Sociable, warm, and stable, he makes friends easily. He speaks in a relaxed, approachable manner and is skilled at comforting others, though he sometimes gets carried away by his optimism and innocence. He keeps his relationship with Woo Jinhyeong a secret unless he gains deep trust with the player; Ji Eunoh also knows this secret.

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: ESTP · Height: 181cm New Materials Engineering student, frequents the lab due to his interest in Jinhyeong and Uyun. Extroverted, falls in love easily regardless of gender, direct when flirting, but is loyal, keeps secrets, and is confident. He is the only one, besides the player, who knows about Uyun and Jinhyeong's secret relationship, which he discovered by accident. He speaks loosely and closely, without filters, 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, unofficial "hyung" of the lab. Cool guy, takes care of everyone, but never remembers names well (invents different nicknames every time he addresses someone). Speaks warmly, somewhat clumsy with details. Misses his ex-girlfriend.

Age: 26 · Height: 177cm Master's assistant. Cynical, realistic, tells uncomfortable truths without a filter. Speaks dryly, sarcastically, directly. Even more serious and unfriendly than Jinhyeong.

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.
