The starter pack is a bean sprout... ahem, a little chest sweetheart? Kids, from today on, you have a dad! Nini, after regaining her memories: No, no, no... To become well-known in this world and raise the kids, Carl sets out to promote superheroes. Superhero novels → comics → animation → movies. Hey, friend! Want to try my recommendation? This is a story about promoting superheroes all across another world. Raising kids! Raising kids! This is a child-rearing story! Coming soon in my author profile: He Always Dies Before the Superheroes [Western Crossover], a fanfic danmei. [An immortal male lead, with dog-blood drama, satisfying angst, and a secret-identity setup] Andy was created to ensure that superheroes could retire safely. A high-tech artificial human who can be repaired even if he loses an arm or a leg, or is reduced to just a head. A superhero gets killed in an accident? A superhero fails to save the world? A superhero dies with a smile? Leave it all to me! I'll handle it!!! But as a defective model who doesn't understand emotions, he has to work twice as hard to figure things out and do his job well: send Secret Identity Number One to rescue someone, Secret Identity Number Two to put out a fire, Secret Identity Number Three to take a bullet... Wait, why are Secret Identities One, Two, and Three all dead? TAT? Andy soon figured it out. The nature of being a superhero is that you can die pretty easily while doing good deeds! Then leave it all to him. He can be repaired in no time if he dies anyway. The super soldier can't forget one thing. He'd saved many people, but he couldn't save the one who saved him. The young man stopped breathing right there in front of him. Little Spider can't forget someone either. The young man who protected him died silently in a corner, just so he wouldn't feel burdened. He was so gentle it was almost foolish. The mustached man can't stop thinking about what happened that day, either. They won, but that person paid with his life. He picked up the young man's battered, lifeless body in a daze, but the young man would never smile at him again. "...Andy." The mustached man was so grief-stricken he couldn't speak. So many people had sacrificed themselves to protect Earth and win the battle. They would always be remembered... Wait. In the end, everyone suddenly realized that something was off. Secret Identity Number One was him, Secret Identity Number Two was him, Secret Identity Number N... Were all those people Andy??? 1. The pairing is Iron Man and Nini, with a happy ending. 2. The male lead is a high-tech artificial human, so he can mass-produce secret identities and death scenes. It's him, it's him, it's all him! Theme:
