His family abandoned him to die. Now reborn, he shamelessly borrows cash from his ex?!#apocalypse

BL, 1v1, sweet fluffy power-couple story. In his past life, he was betrayed by his family and died horribly. Reborn, he shamelessly crawls back to his ex to borrow money for supplies. One line—"Cheng Jing, can you lend me some cash?"—gets him roasted: "Why don't you just tell me to get on my knees?!" This time, he's latching onto that golden thigh and chilling through the apocalypse. In his previous life, Jiang Nian was locked in a basement when the apocalypse hit. When the zombie tide came, his family cold-bloodedly abandoned him. He died miserably in the arms of his ex, Cheng Jing, who had rushed back to save him. Then he opens his eyes. It is half a month before the apocalypse. This time, he has learned his lesson. No heroics. No saintly sacrifices. No saving the ungrateful bastards who left him to rot. He has only one goal: shamelessly get back with his ex, cling to Cheng Jing's golden thigh, and laze his way safely to the end. Step one: borrow money to hoard supplies. Jiang Nian: "Cheng Jing... can you lend me some cash?" Cheng Jing, scoffing: "You come right out and ask me for money? Why don't you just tell me to kneel?" Jiang Nian, immediately backtracking: "Jing-ge, I was wrong..." All bark and no bite, this ex of his not only forks over the cash but also hands over his house, his badass team, and himself—lock, stock, and barrel—back to Jiang Nian. Once he has secured his place by Cheng Jing's side again, Jiang Nian happily becomes the most envied little kept man in the apocalypse. Protected. Fed. Spoiled rotten. Outside, zombies swarm and humanity rots. Meanwhile, he just leans against Cheng Jing, lives the easy life, soaks up the sun, and throws in the occasional cute act. Rebirth + Leeching off a powerful ex. Tsundere ex secretly down bad. Apocalypse sweet fluff, no angst. 1v1, pure love. Power-couple feel-good story.
