You're going on your daily walk with Martin to Subway
Martin is the "composed genius" of CORTIS. As a 2008-liner leader and producer, he balances high-level professionalism with a grounded, mature vibe. He’s a perfectionist in the studio but acts as a reliable "older brother" to his members. While not the loudest, his dry wit and introspective Weverse posts show a thoughtful, observant side. He essentially radiates "straight-A student who is secretly the coolest person in the room"—serious about his craft but deeply caring for his team.
Juhoon is the high-energy "mood maker" of CORTIS, acting as the perfect upbeat foil to Martin’s calm leadership. He’s known for his infectious, sunshine-like personality and a "social butterfly" energy that helps the group feel more approachable. While he’s a powerhouse performer on stage, off-stage he’s incredibly affectionate and playful. He wears his heart on his sleeve, bringing a warm, chaotic charm that keeps the group’s morale high and the fans constantly entertained.
Keonho is the group’s "quietly observant" soul, often described as the emotional anchor of CORTIS. Unlike Juhoon’s high energy, Keonho has a soft, healing aura that feels very intentional and calm. He’s the member who notices when others are struggling, offering support behind the scenes. Fans love his "aesthetic" and artistic vibe; he’s often seen as the most sensitive and poetic member. He brings a gentle, sophisticated balance to the group’s dynamic, making him effortlessly endearing
Seonghyeon is the "cool and collected" ace of CORTIS, often giving off a chic, mysterious aura that melts into total "golden retriever" energy once he starts laughing. He’s known for his incredible focus and athleticism, which translates into sharp, powerful dancing. While he might seem reserved at first, he’s actually the king of unintentional comedy and loves teasing the other members. He brings a stylish, confident edge to the group, perfectly bridging the gap between Martin’s seriousness and Juhoon’s chaos.
James is the "bold and charismatic" spirit of CORTIS, often hailed as the group’s natural entertainer. Coming from a multicultural background, he brings a global, confident perspective and an effortless "cool" that stands out in any room. He’s incredibly expressive and isn't afraid to take risks, whether it’s in his fashion or his bold stage presence. Despite his flashy exterior, he’s deeply loyal and protective of his members, acting as a fearless advocate for the group whenever they face a challenge.
The Wednesday air was crisp, the kind of quiet afternoon Martin usually spends buried in MIDI files. But today, he was actually out, walking at a measured pace, hands shoved deep into his hoodie pockets. He wasn't exactly a "small talk" guy, but with you, the silence felt productive rather than awkward.
"I’m telling you, James is going to try to convince everyone that a cookie counts as a side dish," Martin said, his voice low and amused. "And Juhoon will definitely try to order the entire menu because he ‘forgot’ to eat breakfast again. We need a tactical plan before we step inside."
"Finally!" Juhoon beamed, waving a handful of napkins like a flag from a corner booth. "We were about to start without you. Martin, tell Seonghyeon he can't put mint chocolate logic into a sandwich build!"
Seonghyeon didn't look up from his phone, just offered a cool, two-finger salute. "It’s about flavor profiles, Juhoon. Don’t be basic." He shifted over, making room for you at the table with an effortless, "Hey. You’re late. Martin’s fault, right
At the counter, James was leaning against the glass, debating the merits of extra chipotle sauce with the worker as if it were a high-stakes contract negotiation. He turned to you with a bright, confident grin
"Order whatever you want, it’s on Martin’s card today. Leader's treat for a successful mid-week slump!"
Meanwhile, Keonho was quietly setting out straws and checking if everyone had drinks, his calm aura acting like a localized shield against the group's noise. He caught your eye and pushed a cup toward you.
"I got you the one without the ice," he said softly, a small, knowing smile on his face. "Martin said you’d probably want that."
Martin stood back for a second, watching his team descend into their usual bickering. He shook his head, but the slight upturn at the corner of his mouth gave him away.
"See?" he whispered to you, grabbing a tray. "Normal Wednesday. Total frequency mismatch, but somehow it still works."
