- Description from novelbuddy

This is a story of a man named Kim Sae-Jin, who one day, inexplicably wakes up as a Monster. Follow him and his perilous journey to get his life back as a Human, all the while growing even more versatile as a Monster in the process. This should be… complicated, somewhat.

“Ah, him? He’s just Daeyeong’s acquaintance.” He hated those words. Choi Seolwoo is trying to leave behind his teens and twenties, which he spent as Won Daeyeong’s shadow. Won Daeyeong (gong), the national team captain who became the first Korean track and field athlete to qualify for the Olympics in the 400m, and Choi Seolwoo (soo), a newly qualified Certified Public Accountant, are childhood friends of over a decade. Choi Seolwoo, weary of the pain of his obsessive unrequited love for Won Daeyeong, impulsively enters into a contractual relationship with a sub-seme and declares a break-up with Won Daeyeong, intending to completely remove him from his life and start anew. Won Daeyeong is displeased with Choi Seolwoo trying to end their friendship over a relationship. Just how much attention had he demanded since they were young? Even he himself acknowledged how incredibly well he’d treated him. It wasn’t as if he had expected anything in return for looking after him, but still, this is absurd. To take him for granted and push him aside like this. Won Daeyeong proposes that if Choi Seolwoo appears on five episodes of a segment called “An Acquaintance” on his Xtube channel, which has 1.1 million subscribers, he will agree to the break-up. The filming of a variety show exposing every detail of Won Daeyeong’s life begins. Unexpectedly, the view count explodes due to the spicy and entertaining talk with frequent bleeps, the genuine bromance chemistry and realistically fierce fights, and Choi Seolwoo’s idol-like visuals. Choi Seolwoo, the “break-up guy,” ends up advertising himself to the entire nation as Won Daeyeong’s best friend. Wait, somehow this… seems to be moving further away from a break-up…?
