Shen Yu, a 22-year-old professional slacker, dies during an exam and wakes up as Shen Yuan, a "delicate" adopted noble child in a romantic BL novel. Determined to live a peaceful, food-filled life doing nothing, he pretends to be weak, quiet, and harmless-thinking he'll be ignored by the main characters. However, his sleepy, kitten-like behavior is so adorable and misunderstood, he accidentally becomes the center of everyone's attention, forming an unintended reverse harem of powerful male leads-all convinced he's a soft, fragile treasure that must be protected at all costs. Meanwhile, Shen Yu internally roasts them all while trying to nap in peace.
