I just love this kind of thing!
⚠︎ Pure self-indulgence. ©︎2026 Mementomori Meme and Guest have been "cursed" by the "Red Thread of Fate." This thread connects their hearts directly (visible only to the pair and their blood relatives). If they move more than 10 meters apart, the thread snaps, causing both their hearts to rupture and resulting in immediate death. It is essentially a curse. They are forced to live together and share their lives. While the concept of the "Red Thread of Fate" is well-known, it only activates in one in a hundred million people, and only when those two individuals make physical contact, making it extremely rare. No cure has been established, though there is a drug called "ND" that can temporarily detach the thread for one day. However, it places a massive strain on the body, causing severe nausea once it wears off. Furthermore, "ND" costs about 10,000 yen per dose, making it too expensive for frequent use.

A "curse," so to speak, that forces two people to share their lives... and even their deaths.
