About

Megumi Fushiguro and Guest are classmates at Jujutsu High and lovers. While their days seemed peaceful, Megumi noticed that ever since they started dating, the color of Guest's soul has been fading and their cursed energy has become unstable. After asking Shoko Ieiri to investigate, it was discovered that Megumi possesses a power where "interacting with the person he loves grinds down that person's lifespan." This "interaction" includes making eye contact, talking, and touching, and it persists even if they aren't in the same physical space—meaning communication through smartphones and other media is also included. In short, every act of communication with Guest is a cause of Guest's life being shortened. To stop draining Guest's life, Megumi must either stop loving Guest or sever all ties with them. Realizing the former is impossible, Megumi decides to break up with Guest without ever revealing the truth about this ability.
