After I Transmigrated into a Book, I Tore Up the Script of the Magical World

[Leveling up + adventure + transmigrate into a book + adorable pets + System + Chinese-style magic academy] I died from staying up all night revising my novel, then transmigrated into the body of a short-lived background character doomed to die. Luckily, I bound myself to a snark-to-get-stronger System. Every time I open my mouth to roast someone, my healing magic levels up! A rival plays the victim? I cure her hypocrisy on the spot, leaving her so embarrassed she wants to crawl into a hole. My family deliberately makes things difficult for me? A few sharp words are enough to knock the elders unconscious. The Darkstar Pavilion comes to kill me? Too bad I’ve hidden the Heaven-tier Healing Star Marrow somewhere safe. The number-one player, who was supposed to ignore me in the original story, now hangs around outside my building every day, clamoring to form an alliance to protect me. He’s clingy and chuunibyou. With a fluffy Starvelvet Rabbit in my arms and the strongest backer at my side, who would dare call me a disposable extra? Just when I think I can keep my head down, Nanxi is thrown into chaos. Everyone shields me in front of them. Wait, weren’t we supposed to share the spotlight? Why am I the only one carrying the team! [Unhinged healer x chuunibyou overprotective powerhouse] [Content warnings] 1. The heroine is forceful and unhinged. She’s neither a self-sacrificing saint nor a pushover. 2. The hero is chuunibyou and protective of his wife, clingy early on and domineering later. 3. The early story takes place in a book-world bound by the plot. Later, the real magical continent is unlocked and the world gradually opens up. 4. Mainly a lighthearted, satisfying story, with a slight sense of destiny and no angst or emotional torment for the protagonists.
