After waking up inside a novel, a struggling man finds himself trapped in a far harsher reality than expected, burdened by endless financial hardship. Things become even more complicated when he is unwillingly forced into becoming someone’s “rut partner,” entangling him in a relationship driven by instinct, desire, and confusing emotions. Just as the connection abruptly ends, leaving behind lingering emptiness, he encounters another man whose presence eerily reminds him of the one he can’t forget.
