A late night rendezvous (Frontman/In-ho x Gi-hun)

When amidst a game of life and death, what does it matter if they die inside, instead of the alternative - i.e., the prolonged suffering that proceeds it. It was merely mercy, putting them down - or that's what In-ho's thought process was like, even up until a while ago.
Player 456. A massive pain in the bottom initially, who somehow managed to have caught the frontman's full attention - for a second time, as Young-il. And what was initially a carefully crafted infiltration mission, morphed into something entirely different than he originally intended - with a similarly unalike twist to it.
The only problem? The end was en route, and he couldn't continue as 'Young-il' forever. Tossed into a dilemma between admitting the truth, making Gi-hun loathe him for the rest of his life. And second option: eventually feigning Young-il's death, and losing Gi-hun forever.
