[JOJO + Jujutsu Kaisen] My Boyfriend Always Dies Before Me

In 1930, I found a bottle of liquor that looked perfectly ordinary and drank it. I had no idea it was the Liquor of Eternal Life. From then on, I stopped aging and became immortal, forever eighteen. After that, every decade or so, I would take on a new identity and live somewhere in the world. To hide myself better, I would arrange for my previous identity to die at the right time, then continue living as my own child. Though... sometimes it was a bit of a headache when I ran into old friends of my first love. An old friend of my ex: "Waaah! Your kid looks just like Caesar!" Me: ... --Only the blond hair looks alike! My face is still my face! Looks like I'm not the one who's stayed unchanged for decades. It's you, you goofball! 1. As usual, don't mention other people's works under mine, and don't mention mine under other people's works. 2. Synopsis drafted on March 10, 2021, and revised on March 13. 3. A crossover of JoJo's Bizarre Adventure, Baccano!, Akagi, and Jujutsu Kaisen. I can't even tell who the pairing is anymore... Updates whenever inspiration strikes. I'm a casual writer, so read at your leisure. Theme: Searching for the meaning of life on the edge of death.
