The Sickly Beauty Became Everyone's Favorite with a Sharp Tongue

Dual male leads / transmigrate into a book / sweet with a touch of angst / mildly goofy POV: Primarily the bottom’s perspective, with brief interludes from the top’s perspective Character profiles: • Bottom, Xie Chichi: In real life, he has congenital heart and lung dysfunction and gets winded after taking a few steps. But he’s a master of verbal sparring, and his sharp tongue somehow comes off as “cute.” • Top, Jiang Yan: A minor background character and the second male lead in the original novel, he’s the real young master of a wealthy family. He seems sunny and fit on the outside, but he’s secretly devious, talks nonstop, and is even more sharp-tongued than the bottom. Blurb In real life, the most strenuous exercise Xie Chichi gets is using his phone to insult people. One day, he transmigrates into a novel about the true and fake young masters of a wealthy family, becoming the sickly, beautiful fake young master who dies young. System: Your mission is to survive and make the real young master, Jiang Yan, fall in love with you. Xie Chichi: “...You might as well ask me to pluck the sun from the sky. I’d have better odds.” Later Jiang Yan, the real young master, pins Xie Chichi against a wall, brushing his nose against the earlobe flushed red from Xie Chichi walking a few extra steps. “Chichi, the doctor says I’m low on vitamins. What do you think I’m missing?” Xie Chichi, panting, sneers, “A conscience.” Jiang Yan: “No. You.” Onlookers: ...So even heirs to wealthy families get this cheesy when they fall in love.
