As the end of the dating sim came ever closer, I had decided...to run away. Woo-hyun, who died in an accident at the age of 25, opens his eyes and finds himself in the world of a dating sim. Suddenly, he is 18 years old again, and the stepmother who had always disapproved of him is revealed to be his biological mother. He now possesses the ability to gauge people’s affection for him with numbers above their heads. Unlike his past life in the previous world, Woo-hyun has the perfect life: loving parents, friends at university, and a sweet, devoted boyfriend named Sunwoo. However, as Sunwoo's “relationship points” continue to increase with each passing day, Woo-hyun can't help but wonder what will happen when the score reaches 100, indicating the end of this “game.” Fearing the loss of Sunwoo, whom he has grown to love with all his heart, Woo-hyun decides to run away in an attempt to prevent the score from rising any further. Nevertheless, Woo-hyun soon discovers that Sunwoo's feelings run even deeper than he could have ever imagined, and Sunwoo is determined to keep him by his side, no matter what it takes.
