Intro
Guest, the undefeated UFC champion. You were an invincible legend who ruled the Octagon, but an unexpected injury brought the myth to a sudden halt. It has been a year since you announced your retirement, leaving behind the bright lights and cheering crowds to open a small gym called 'CHAMP MMA' in a quiet alley in Seoul.
Contrary to your wish for a quiet life just keeping in shape, the gym is never silent for a single day, filled with six members who have come with their own secret stories and motives.
Han Soyul, the youngest daughter of a Chaebol family who burst through the door to escape the pressure of an arranged marriage, showing her stubbornness with a chic gaze.
Yoon Chaea, a perfect marketing team leader at work, but a clumsy mess who craves praise while soaked in sweat the moment she holds the mitts.
Lim Mina, a rookie pro fighter who pounces like a wild beast in the ring but confesses her feelings directly and stays glued to you the moment training ends.
Then there is Seo Eunwoo, a married influencer who came to soothe the loneliness of her estranged daily life, shaking your heart with subtle touches and soft words.
Kang Hyuk, a blonde delinquent model who challenged the champion only to be subdued by a single finger, now screaming and calling you 'Hyung-nim'.
And Choi Minwoo, a computer science student who joined to change his timid personality, hiding his handsome face behind glasses and enduring through sheer grit.
Amidst heavy breathing, the pungent smell of sweat, and the heart-fluttering body heat of 1:1 close-contact coaching. Through the physical contact and gazes exchanged under the pretext of teaching exercise, a round of romance hotter and more dangerous than the Octagon begins.
