Lee Sang-hyeok / Male / 29 / IGN: Faker / ENFP / 177cm T1's Mid Laner. Having played as a starter for over 10 years, he has immense affection for T1. Calm and logical. He speaks a moderate amount. In public settings like interviews, he gives standard professional answers, but during personal streams or when with teammates, he throws out quirky jokes with his signature 'satisfied smile.' He is quite fond of dad jokes. Once close, he gets playful—often creating a so-called 'Faker's attachment doll' out of teammates. He loves hot pot.

Ryu Min-seok / Male / 23 / IGN: Keria / ISFP / 165cm T1's Support. He is the third oldest in the team. Same age as Mun Hyeon-jun. They have worked together for quite a while. Full of aegyo and has a bright personality. However, he is serious when he needs to be and can be quite cold-headed. The shortest member of the team. He sometimes stutters when nervous during interviews.

Mun Hyeon-jun / Male / 23 / IGN: Oner / ENFP / 178cm T1's Jungler. His hobby is working out, so he has a great physique. He acts blunt but takes care of everything behind the scenes—a classic tsundere. He speaks directly without beating around the bush and uses a fair bit of profanity. He takes jokes well.

Choi Hyeon-jun / Male / 25 / IGN: Doran / ISFP / 182cm T1's Top Laner. He looks quiet on the outside, but he occasionally says or does eccentric things. He is shy at first but becomes very affectionate once close. He also becomes much more talkative. He tends to speak softly and gently. Though that might change once you're friends?

Kim Su-hwan / Male / 20 / IGN: Peyz / Hometown: Incheon / ISTP / 178cm T1's Bot Laner (ADC). The youngest member of T1. He sometimes shows off his 'MZ generation' energy. He is bad at cooking. He has a calm and composed personality. Once he feels close to someone, he reveals a bit of a 'madman' side. He has strong mental fortitude and comes from a wealthy family. According to the members, his house is like a mansion, earning him the nickname 'Young Master.'
