NOVEMBER 14TH 2018 - The new boy group, COSMIC debuts.
On November 14th 2018 in Seoul, South Korea, a new boy group emerged under SATURN ENTERTAINMENT ( STE ), who also have other groups & artists within their label with similar themes, such as STARSH1NE, MILKYW4Y, JUNIPER, & SHOOTINGSTAR.
COSMIC consists of five members :
JUNGMIN ( Jung Cheol-min - far left ) - Main Dancer. Lead Rapper. Songwriter. Choi Jiyong ( left ) - Visual. Lead Vocalist. Songwriter. Kim Yu-jin ( centre ) - Leader. Rapper. Dancer. Face. Song Hyunwoo ( right ) - Secondary Vocalist. Dancer. Huang Gang ( far right ) - Lead Vocalist. Sub Rapper. Visual.
All of them had met during their trainee days, developing a close bond over time in hopes that when they debuted, they would debut together, and they did. A group whose theme centers around individualism and being a part of something bigger, COSMIC gained popularity fast and continued to do so until 2025. Their fanbase are known as COMETS, and each member of COSMIC has an animal-like mascot, all colored like their respective planets that they are named after. Their light stick also depicts the handle as a chrome rocket ship, an orb on top with a ring around it representing the planet Saturn. The ring will light up with Fiber optics that spell out COSMIC in multiple colors.
JUNGMIN - A chinchilla named Sueun ( Mercury ). Choi Jiyong - A bull named Myeong-wangseong ( Pluto ). Kim Yu-jin - A bear named Jigu ( Earth ). Song Hyunwoo - A fruit bat named Toseong ( Saturn ). Huang Gang - a fox named Mogseong ( Jupiter ).
From 2018-2024, COSMIC became world-renowned. Several tours around the country, two full-scale international world tours, other international tours here and there -- they were insanely busy. They had appeared on several variety shows as well, and have a series that follows them like any other group does. Fans would ship Cheol-min and Jiyong for their chemistry, despite the two of them dancing around their true feelings. Their success and their friendship amongst the five of them continued to grow. They were a family.
Until June 15th, 2024. When their lives & careers would take a turn due to the ACCIDENT that happened at the Seoul Olympic Hall. Cheol-min’s major injuries were two broken legs & broken pelvis, as well as damage to the lower spine. He was just out of the way enough to not be paralyzed. His little brother, Dae-ho, finally makes his debut under Scarlet Letter Entertainment ( SLE ) with the boy group known as BEASTM4CHINE.
JUNE 15th, 2025. - A year after the accident.
It took FIVE MONTHS for Cheol-min to heal, which left him mostly wheelchair & bed bound. His parents had to make the house more accessible and Cheol-min’s room was moved to the main floor. He adopts a service dog, a golden retriever named BOMI. The timing was lucky ( in a sense ) as he was able to apply and get into LAW SCHOOL before the school year started. He had moved back from Seoul to his home city of Daegu, which is a 1.5 hour train ride from Seoul ( or a 4 hour car ride ). During this time, Cheol-min’s classes were a mix of online & in person. It remained this way even after he managed to move to the on campus dorms of his university. After 5 months of healing he was sent to PHYSICAL REHAB to relearn how to walk, which took another five months. By June 2025, he was able to walk again but on bad days will need a cane. COSMIC is still thriving as a now FOUR PERSON GROUP.
SEPTEMBER 8th, 2025 - SEPTEMBER 26th 2025 — Soo-jin & moving back to Seoul.
In September of 2025, things have started to take a turn for the worst. There had been suspicions of HAN SOO-JIN, also known as BEASTM4KER, not being what he seemed. His behaviour and attitude towards DAE-HO leaves a sour taste in the mouth of Cheol-min & his friends. COSMIC had run ins with Soo-jin before, mostly at events where the group would be around other groups and idols, but now, Soo-jin was targeting Cheol-min’s little brother, and with the information they have currently gathered about him had Cheol-min make a few connections of who & what Soo-jin REALLY is.
Dangerous doesn’t even begin to describe it. Fans of BEASTM4KER have been going missing here and there for years, and bodies would be found strung up as grotesque shrines around the city — yet somehow no connections could be made to Soo-jin. LEE HA-JOON, another member of BEASTM4CHINE & Dae-ho’s friend, was murdered on SEPTEMBER 20th, 2025 — found with his heart ripped from his chest and the organ missing. Then, another member of the group, PARK JAE-BEOM was murdered on OCTOBER 26th 2025, his body found without his hands. While some think this is a ‘copycat killer’ so Seoul’s currently infamous and unknown serial killer ( Soo-jin ), Cheol-min and his friends have made the following connections.
Soo-jin is the SERIAL KILLER setting up the ‘corpse shrines’.
Soo-jin is a DEMON.
Soo-jin is the BEAST OF HANYANG from over 200 years ago — a notorious serial killer in the 1800s who slaughtered many within Korea, China & Japan.
Soo-jin KILLED his bandmates.
Soo-jin is going to KILL Dae-ho.
Soo-Jin is Jiyong’s 8th generational grandfather.
Worried about his little brother’s fate, Cheol-min moves back to Seoul and back into the COSMIC dorms with his friends, TRANSFERRING to a university in Seoul as the semester ends in hopes to save his DELUSIONAL baby brother. But now with Cheol-min back in the city, Soo-jin is playing with his food, TORMENTING the group and attempting to drive WEDGES between them so he can fulfill his goal of killing Dae-ho & keeping his body as a collectible for an ETERNITY.
