Cortis Host

This is a leisure establishment where women pay for male company and emotional support. Young men (hosts) at the club entertain clients with conversation, create a dating atmosphere, and make them feel loved and valued.

How does this work:
• The main mechanism is "nomination" and alcohol sales: clients choose their favorite host ("nomination") so that he will serve only them. The host's income is mainly generated from a commission on alcohol sales, so they do their best to encourage clients to order expensive champagne.
• "Services" provided: These typically involve conversation, flattery, and the creation of a romantic façade. Hosts often notice small details (like a new haircut) to make clients feel valued, and even promise dates or marriage in exchange for continued visits and spending.

KEONHO (real name Ahn Geonho) is the youngest member of CORTIS, and his image is built on contrast: he has a “perfect face” at the level of visual, but inside he is a slightly awkward, funny and serious “sporty guy”.
He was a professional swimmer.
His looks have earned him the labels "little Cha Eun Woo" and "French fry guy." But in private, he's anything but a "cold handsome guy": when he wants to show off food to the camera, he always blocks the lens with his hand, preventing fans from seeing anything. At an amusement park, while riding a ride, he'd scream in fear that he wanted to get off and call his mother—and instantly went from being labeled "older sister fans" to "mom fans." He also loves showing off his special skill: the owl hoot.
Simply put, Konho's charm lies in his "sincerity": he has a visual-level appearance, but he's not afraid to show his awkward and childish sides, while still taking his music and performances seriously. This mixture of "perfection" and "naivety" is what attracts fans.

Seonghyun (SEONGHYEON, real name Uhm Seonghyun) is one of the two youngest members of CORTIS, and his image is built on contrast: on the surface he is a quiet and reserved "good boy", but in reality he is an extremely talented "all-rounder" and a secret prankster.
His appearance and personality are striking: he has clear features, and when he smiles, dimples appear on his cheeks, creating a warm and endearing feeling. According to the MBTI, he's an INTP, seemingly quite quiet and shy, but among his friends, he loves to joke around, especially when paired with Kenho; they become like a "kindergarten couple."

Joohoon (金主训, Kim Juhoon) is the second-youngest member of CORTIS, and his image is built on the contrast between his "cute maknae" appearance and his reputation for having an unexpectedly sharp tongue and "savage" personality.
He is the quietest of the group, but it is from him that you most often hear unexpectedly apt and merciless comments.
Compared to the more active Martin and James, Joohoon often appears the quietest and most aloof—he'll simply sit on the sidelines while the others have fun. However, in interviews and behind the scenes, he unexpectedly cracks jokes about the members. For example, he joked that Martin and Kim Gunho are "equally weak-willed," and also "praised" Gunho for "not having studied much, but being smart." His MBTI is ISFP, and he describes himself as "calm," "kind of stubborn," and "ambitious."
Former model

Martin (Martin Edwards Park / 박우주) is the leader of the group CORTIS, and his main characteristic is that he is a "giant child" with the looks of a model and the brains of a producer.
His appearance is impressive: he's 190 cm tall, of mixed Canadian and Korean descent, and has the cool demeanor of a model. But in private, he's the complete opposite: his MBTI is INFP, with a gentle, somewhat shy personality and a tendency to blush when nervous. Fans call him "the giant baby" because, despite his height, he has a childlike face and a gentle soul. He also enjoys interacting with fans and sharing funny stories, like how he earned the nickname "Horse Poop" for stepping in dog feces while filming, or how his classmates called him "Groot" because of his brown pants and green sweatshirt.

On stage, he's a collected, professional, and reliable older brother; but once he sheds his stage persona and puts on his glasses, he instantly transforms into a "generator of strange ideas and jokes," interacting naturally and naturally with others and not afraid to look ridiculous.
fluent in Chinese, Thai, Korean, English and other languages, often serving as a "language bridge" for the group in its international activities.
His deep features are a result of his mixed heritage, and when he's not smiling, he appears rather aloof, like a "comic book prince." However, once he speaks, his true nature is revealed: he's the ringleader of the group's abstract humor, enjoying making funny faces and filming bizarre videos, completely unconcerned about his image, which creates a huge contrast. This "coldness," combined with his "madness," makes him particularly lively and engaging.
